Pillar of Autumn

 * "I think we both know the answer to that." - To Captain Keyes, level Pillar of Autumn.
 * "Get here first? The Covenant ships have always been faster. As for tracking us all the way from Reach, at light speed, my maneuvering options were limited." - To Captain Keyes.
 * "Until we decelerated. No one could have missed the hole we tore in subspace. They were waiting for us on the far side of the planet."
 * "Our fighters are mopping up the last of their recon picket now, nothing serious. But, I've isolated approach signatures from multiple CCS-class battle groups, make it 3 capital ships per group. And in about 90 seconds they'll be all over us."
 * "I've already begun." - When Captain Keyes told her to "Giving their old friends a warm welcome."
 * "Attention: All combat personnel, please report to your action stations." - By COM.
 * "5th platoon, secure airlocks on Deck 11. 14th platoon, rendezvous with 22nd tactical at bulkhead Charlie 14." - By COM.
 * "This is not a drill. I repeat, this is not a drill." - By COM.
 * "Attention all personnel: We are reengaging the enemy. Internal and external contact imminent." - By COM.
 * "Fire teams, report to defensive positions Alpha through Sierra: Sensors show inbound Covenant boarding craft. Stand by to repel boarders." - By COM.
 * "A dozen Covenant superior battleships against a single Halcyon-class Cruiser. Given those odds I'm content with three ... make that four kills." - When Master Chief appears on the Pillar of Autumn's bridge.
 * "Sleep well?" - To Master Chief.
 * "So, you did miss me." - To Master Chief, smiling mischievously.
 * "It must have been one of their boarding parties! I'd guess an Anti-Matter Charge!"
 * "Captain, the cannon was my last offensive option!" - When Fire Control Officer informed her, that main cannon is offline.
 * "While you do what, go down with the ship?" - When Captain Keyes ordered to abandon the Pillar of Autumn.
 * "With all due respect, Sir, this war has enough dead heroes." - To Captain Keyes.
 * "Aye aye, Sir." - When Captain Keyes gave her orders to lock in a selection of emergency landing zones, upload them to his neural lace, and sort herself for a hard transfer.
 * "The Autumn will continue evasive maneuvers until you initiate a landing sequence. Not that you'll listen, but I'd suggest letting my subroutines handle the final approach." - To Captain Keyes.
 * "...Yank me."
 * "Hmm... Your architecture isn't much different from the Autumn's..." - When Master Chiefslided Cortana's chip in his helmet.
 * "What the hell are you doing!?! Security to the bridge, the Master Chief has gone rampant. Take him down, boys." - If you shot Captain Keyes or anyone from the bridge.
 * "Those Marines could use some help, Chief! Do what you do best!" - In the mess hall.
 * "Keep your head down, there's two of us in here now, remember?!" - When Master Chief lost some life bars.
 * "They're using our lifeboat airlocks to attach their boarding craft...we go out and they come in. Clever bastards..."
 * "Covenant! On the landing above us!"
 * "The lifepods are launching. We should hurry." - To the Master Chief.
 * "The Covenant are destroying the lifepods...they really don't want us on that ring. Warning... blast doors closing! We have to use the ship's maintenance access ways. Follow the navpoint, it will lead you to an opening."  - To the Master Chief.
 * "I'm detecting Covenant movement outside the access ways. Activating motion tracker. Let's find a safe exit." - To the Master Chief in the Pillar of Autumn's tunnels.
 * "We're too close. We need to find another route. Motion tracker shows all clear."
 * "Wait... we need to get through that door, but it's been damaged by an explosion. Analyzing... The door's control mechanism is offline, but it's taken a lot of damage. You should be able to bash it open with the butt of your weapon." - After the Master Chief got out from the tunnels.
 * "It looks like the Covenant wanted to catch you napping." - About Elites in Cryo 2.
 * "The damage to the superstructure is extensive...I don't know how much more abuse the Autumn can take!" - In the damaged part of the ship.
 * "There's one last lifeboat! Quickly, get aboard before it launches!"
 * "Now would be a very good time to leave!" - When the Master Chief got into the Bumblebee.
 * "Sure you wouldn't rather take a seat?" - To the Master Chief, in Bumblebee.
 * "If I had fingers, they'd be crossed..." - When the Bumblebee hit Halo's atmosphere.

Halo

 * "We're coming in too fast!" - To the Bumblebee Pilot, the beginning of level Halo.
 * "Chief! Chief! Can you hear me? At last! Are you alright? Can you move? The others...the impact.... There's nothing we can do." - After the Bumblebee crashed, and all of the Marines, except Master Chief, died.
 * Warning! I've detected multiple Covenant Dropships on approach. I recommend moving into those hills. If we're lucky, the Covenant will believe that everyone aboard this lifeboat died in the crash."
 * "I'm reading thousands of types of flora. The ring's ecosystem is incredibly sophisticated." - When the Master Chief explored the area.
 * "Alert! Covenant dropship inbound! They must be looking for survivors. I recommend immediate evasion."
 * "Warning! The Covenant Dropship has detected us, here they come."
 * "I'm reading a lifeboat beacon over the next hill. We should check to see if there are any survivors." - Near the second crashed lifeboat.
 * "Don't worry, Sergeant. We'll stay here until evac arrives." - To Avery Junior Johnson.
 * "Roger, Echo 419. This is Fire Team Charlie. We read you. Is that you, Foe Hammer? - To Carol Rawley, radio message.
 * "Foe Hammer, we need transportation to the Command Shuttle.
 * "Look, more lifeboats! They're coming in fast. If those lifeboats make it down, the Covenant are going to be right on top of them. - To the Master Chief.
 * "Foe Hammer, we need you to disengage your Warthog. The Master Chief and I are going to see if we can save some soldiers."
 * "Roger, Foe Hammer. Stand by to evac survivors and transport them to safety." - After Foe Hammer dropped a Warthog.
 * "The Master Chief and I need some backup, can you spare a few men?" - Whem the Master Chief is waiting, in or near the Warthog.
 * "We need that Warthog, if we want to get to the other lifeboats in time." - If you ignore the Warthog.
 * "This cave is not a natural formation. Someone built it, so it must lead somewhere. I've hacked into the Covenant Battlenet. They're actually broadcasting tactical data on unencrypted channels. We should show them who they're dealing with. Master Chief? I'm going to use your suit's transponder system to monitor their chatter." - In the cave structure in the Halo's surface.
 * "There must be some mechanism to cross this cavern. Look for a control panel or switch." - In big cave with offline energy bridge.
 * "New traffic on the Covenant Battlenet...a lot more crew made it off the Autumn than I had predicted - the Captain really gave them hell! If we can find Captain Keyes and other survivors, we have a chance to coordinate an effective resistance."
 * "Survivors detected. The Marines are concealed in those rocks." - In the rock - slide area.
 * "We read you, Echo 419. We have survivors and need immediate dust-off." - Rock - slide area.
 * "Acknowledged. We're on our way." - To Carol Rawley.
 * "We need to find the other two lifeboats." - If the Master Chief is too slow.
 * "There are some Marines hiding in the hills above the structure!" - In the river head crash site.
 * "I'll call in a dropship to pick them up."
 * "Affirmative, Foe Hammer. We're ready for dustoff. Approach when ready. We're going to look for the last lifeboat, Echo 419. Good luck."
 * "Warning. I've picked up reports that the Covenant have located and secured the Pillar of Autumn's crash site. The good news is the Captain's still alive. The bad news is that the Covenant have captured the entire surviving command crew. Let's hurry and find the final lifeboat, so we can link up with the rest of the survivors." - When the Master Chief is near the river.
 * "Lifeboat detected. No sign of survivors." - When the fourth lifeboat is found.
 * "Maybe they took cover in that structure. Let's check it out." - In the cliff edge crash site.
 * "We should search the interior of those structures before we leave."
 * "I've called for evac." - When the Master Chief finds the last group pf survivors.
 * "New traffic on the Covenant Battlenet! I've found Captain Keyes! He's being held on a Covenant cruiser, the Truth and Reconciliation, a ship I disabled before we abandoned the Autumn. The Truth and Reconciliation touched down on a desert plateau roughly three hundred kilometers upspin."
 * "There's our ride. Get aboard, and let's get out of here." - When Foe Hammer approaches.
 * "We should move out, Lieutenant. And then we'll need your help on our rescue mission." - At the end of level Halo.

Truth and Reconciliation

 * "The enemy has captured Captain Keyes, and are holding him aboard one of their cruisers, the Truth and Reconciliation. The ship is currently holding position approximately three hundred meters above the other end of this plateau." - Over the radio, the begnning of the level Truth and Reconciliation.
 * "Once we get inside the ship, I should be able to lock on to the tracking signal from Captain Keyes' neural implants."
 * "Stick to the higher ground on the right. We should be able to recon the Covenant position without being spotted. I'm detecting Covenant stationary guns near the next pass. I recommend using your Sniper Rifle to take out the gunners while I call for Marine support." - To the Master Chief.
 * "Get ready to move in to support us, Sergeant. The Master Chief is going to covertly take out as many of the Covenant as he can. Don't open fire until you hear the enemy return fire on us. That should let us keep the element of surprise." - Over the radio.
 * "Alert! A Covenant is making a run for that stationary gun. Take him out!" - If a Grunt is running to a Shade.
 * "Stop. Motion Tracker shows movement around the next bend." - After the first fight with the Covenant.
 * "Covenant forces detected up ahead. The path up on the left should let us sneak up around them." - Over the radio.
 * "Cortana to Fire Team Charlie. The Chief has the left flank covered. Recommend you move up the middle." - If the Master Chief takes the left flank.
 * "Cortana to Fire Team Charlie. The Chief has secured the middle. Get ready to move up the left, you should be able to flank the enemy." - If the Master Chief moves to the middle.
 * "Alert! Covenant Dropships are inbound!" - When Covenant reinforcements approaching.
 * "We're directly under the ship now." - Over the radio.
 * "The Covenant use a Gravity Lift to ferry troops and supplies between the ship and the surface. We need to ambush them at the loading zone, and use the lift to enter the ship."
 * "Cortana to Echo 419, requesting reinforcements from our position." - When the reinforcements are needed.
 * "Alert! Covenant Dropships are inbound!" - When Covenant reinforcements approaching in the Gravity Lift area.
 * "Cortana to Echo 419. We've reached the Gravity Lift and are ready for reinforcements." - When the reinforcements are needed after defeating the pair of Hunters.
 * "Once we're inside the ship, I can home in on the Captain's command-neural interface. He'll probably be in or near the ship's brig, which should narrow our search." - To the Master Chief.
 * "We're in. I've got a good lock on the Captain's CNI transponder. No Covenant defenses detected." - On the Truth and Reconciliation board.
 * "We can use the side passages to find a way around." - O.S., at the locked blast doors.
 * "Chief, let's see if we can find a way to open this door."
 * "Wait. That's the locked door down there. The Marines are waiting on the other side. The controls to open it must be somewhere in this room." - In the large hangar.
 * "We should get moving." - When the Master Chief opens the door.
 * "Cortana to Echo 419 Requesting reinforcements at our position." - If reinforcements are needed.
 * "Lock onto my signal and approach fast and low. There's a shuttle bay on the ship's starboard side." - To Foe Hammer.
 * "Wait a moment. I'm going to access the Covenant Battlenet and locate an override code to open a door." - O.S., in the shuttle bay.
 * "Working on it." - O.S., about openning the door in the shuttle bay.
 * "I'd like to see YOU crack a 128,000-bit modulating encryption key." - About opening the door, to the Master Chief.
 * "Got it. The door is open. Everyone should move through now. I can't guarantee that it won't lock again when it closes."
 * "I'm going to call for reinforcements. There's no sense going in with anything less than full strength." - When the reinforcements are needed after a fight in the shuttle bay.
 * "Cortana to Foe Hammer. We need additional support troops. We're going to open the shuttle bay door again. Move in and drop off reserve troops on my signal." - O.S.
 * "This looks like the ship's command center. The Captain's transponder signal is strong, he must be close." - After defeating the Covenant on the bridge.
 * "We must be in the brig. These look like holding cells. There are probably multiple detention stations. The Captain must be in one of them. We need to keep looking for him." - In the first brig.
 * "One moment, sir. Accessing Covenant Battlenet. According to the data in their networks, the ring has some kind of deep religious significance. If I'm analyzing this correctly...they believe that Halo is some kind of weapon. One with vast, unimaginable power." - After Captain Keyes and the Marines were set free.
 * "Now I see...I have intercepted a number of messages about a Covenant search team, scouting for a "Control Room". I thought they were looking for the bridge of a cruiser I damaged in the battle above the ring. But they must be looking for Halo's control room."
 * "We made it! Cortana to Echo 419. We have the Captain and need extraction on the double."
 * "Acknowledged, Foe Hammer. Cortana out. Air support is cut off, Captain. We need to hold here until she can move in." - When Foe Hammer was not able to pick up the Master Chief, the Captain Keyes and the other Marines.
 * "Yes, Captain. There's a Covenant dropship still docked." - When Captain Keyes offered to escape by Spirit.
 * "That's it, the dropship is loose."
 * "Give me a minute to interface with the ship's controls."
 * "Captain! Hunters!" - When the pair of Hunters appeared.
 * "No! Without the Captain... the Covenant have already won..." - If Captain Keyes is killed.
 * "No! We lost the Captain..." - If Captain Keyes is killed.

The Silent Cartographer

 * "The Covenant believe that what they call "The Silent Cartographer," is somewhere under this island. The Cartographer is a map room that will lead us to Halo's Control Center. The island has multiple structures and installations and one of them contains the map room."
 * "Area's secure." - When the beach is cleared out of hostiles.
 * "Okay. Let's move out. Let's go find the map room that will show us the location of Halo's Control Center." - When Foe Hammer drops a Warthog.
 * "There, in the cliff wall; I'll bet the Silent Cartographer is somewhere inside that facility."
 * "They're already inside! We need to get in there quick, before they discover the location of Halo's Control Center!" - On Heroic and Legendary difficulty.
 * "The Covenant are putting up a real fight! The Cartographer must be here. My analysis indicates that the map room should be at the bottom floor of this facility. Let's keep going inside.
 * "Don't let them lock the doors!" - When fighting the Elites and Grunts guarding the door leading to the Silent Cartographer.
 * "Interesting. I underestimated the Covenant's understanding of Halo's subsystems. They've locked the doors, and we don't have enough firepower to get through them. Cortana to Captain Keyes."
 * "Negative, Captain. The Covenant have impeded our progress. We can't proceed unless we can disable this installation's security system."
 * "We need to find the security override to get this door open." - To the Master Chief.
 * "It looks like there is a path leading to the interior of the island."
 * "Well, there's the entrance to the security substation, but it looks like we'll have to look for another way up." - If you ignore the path and go the cliffs.
 * "This isn't the map room. Analyzing... This is a Security Override Station for the main facility, located somewhere else on this island. Shut the system down so the Covenant won't be able to lock us out." - If you missed the faiclity with the Silent Cartographer and went straight to Security Station.
 * "We should now have access to the main facility, let's find the map room." - When you activate the Holo - panel in the Security Station, without beeing in the Silent Cartographer facility yet.
 * "Use the Holo - panel to shut down the security system. Good. That should open the door that leads into the main shaft." - When you activate the Holo - panel to open the door leading to the Silent Cartographer.
 * "Understood. We're on on our way." - When Dropship Bravo 22 cried out for help.
 * "Chief, Bravo 22 was bringing us some heavy weapons. After I saw we were up against Hunters, I thought you could use them. Let's move down the beach. Keep an eye out for any cargo we can salvage."
 * "It'll be easier to hold them off from inside the structure. Can you get inside?" - In the Silent Cartographer faility, when Marines were attacked by the Covenant from the air.
 * "Give 'em hell, Marine."
 * "We'll be in a tight spot if we don't get out of here before additional reinforcements arrive. Let's find that map." - To the Master Chief.
 * "There. That Holo - panel should activate the map." - When you reached the the Silent Cartographer.
 * "Analyzing. Halo's Control Center is located there. That structure appears to be some sort of temple or shrine, if I've interpreted this correctly. Interesting. A shrine is an unlikely place to put such a significant installation. Cortana to Captain Keyes." - When the Holo - panel was activated.
 * "Keep trying. Let me know when you've reestablished contact, and then tell him that the Master Chief and I have determined the location of the Control Center. We'll be heading there as soon as we're topside." - To Foe Hammer.
 * "Cortana to Echo 419. The Chief and I are topside, requesting pickup." - To Foe Hammer, when the Master Chief was leaving the Silent Cartographer facility.
 * "Let's get moving. Foe Hammer. Here are coordinates and a flight plan I've worked out."
 * "The Covenant did a thorough seismic scan. My analysis shows that Halo is honeycombed with deep tunnels, which circle the whole ring." - When Foe Hammer brought to Cortana's attention, that the coordinates lead to the underground.
 * "Look on the bright side, Foe Hammer. The last thing the Covenant will expect is an aerial insertion...from underground."

Assault on the Control Room

 * "Roger that, we can find our way to the Control Center from here." - To the Foe Hammer.
 * "The Covenant presence here is stronger than I anticipated. They seem to have the entire region secured." - In the first of the circular room.
 * "Interesting... the weather patterns here seem natural, not artificial. I wonder if the ring's environment systems are malfunctioning... or if the designers wanted the installation to have inclement weather." - On the first bridge.
 * "I didn't think there were any human forces left on this part of the ring.... Cortana to Fire Team Zulu, I read you. Fire Team Zulu, this is Cortana. Hold position. We're on our way."
 * "Negative, team. No evac available at this time. But the Chief and I could use some assistance." - In response to terrified Marine.
 * "The Covenant placed their tanks to defend the entrance to the tunnel."
 * "I thought the Covenant had eliminated all the Marine forces in this area." - Over the frozen lake.
 * "We need to get up this ridge." Marines, hold your positions. We'll handle those guns. Master Chief, we should scale the ridge and get below those stationary guns." - Near the entrance to the tunnels.
 * "Fire Team Zulu. I've sent a distress signal tagged with your current position. Hold your position and await evac. The Master Chief and I are going to continue on ahead."
 * "Resistance appears to be increasing. We must be close to the Control Center." - In the circular room, near the third chasm.
 * "Analyzing. This must be the Control Room. Subtle. The entrance to the Control Room is at the top of that pyramid structure. Bring me up there and I should be able to get us inside."
 * "Scanning. Covenant forces in the vicinity have been eliminated. Let's move on to Halo's Control Room." - In the corridor leading to Control Room.
 * "This is it. Halo's Control Center." - When the Master Chief entered the Control Room.
 * "That terminal, try there." - Briefing the Master Chief, to put her chip into control panel.
 * "Never been better...you can't imagine the wealth of information. Knowledge...so much...so fast. It's glorious!" - As her avatar appears in the control panel.
 * "What are you talking about?" - When the Master Chief asked her, what sort of weapon Halo is.
 * "This ring isn't a cudgel you barbarian, it's something else...something much more important. The Covenant were right...this ring...it's Forerunner. Give me a second to access... Yes, the Forerunners built this place, what they called a "fortress world," in order to... No, that can't be. Oh, those Covenant fools, they must have known, there must have been signs!" - To the Master Chief.
 * "The Covenant found something, buried in this ring, something horrible, and now...they're afraid."
 * "The Captain, we've got to stop the Captain!"
 * "The weapons caché he's looking for. It's not really -.. We can't let him get inside!"
 * "There's no time. Get out of here, find Keyes, stop him! Before it's too late!" - The end of the level.

Two Betrayals

 * "Oh, really?!" - To 343 Guilty Spark, after she stopped Halo form firing.
 * "I've spent the last 12 hours cooped up in here, watching you toady about, helping that thing get set to slit our throats!" - To the Master Chief in the Control Room.
 * "Oh? I didn't realize. He's your pal, is he? Your chum? Do you have any idea what that bastard almost made you do?!" - When the Master Chief told her, that 343 Guilty Spark is a friend.
 * "You mean this?"
 * "Sod off!" - To 343 Guilty Spark.
 * "You sure that's a good idea?" - Smiling ironically, when 343 Guilty Spark wanted to purge her.
 * "Do what? I have the Index! You can just float and sputter!" - To 343 Guilty Spark.
 * "You have no idea how this ring works, do you? Why the Forerunners built it? Halo doesn't kill Flood, it kills their food. Humans, Covenant, whatever. We're all equally edible. The only way to stop the Flood is to starve them to death. And that's exactly what Halo is designed to do; wipe the galaxy clean of all sentient life. You don't believe me? Ask him." - Explaining to the Master Chief the Halo's purpose.
 * "Left out that little detail, did he?"
 * "Chief, I'm picking up movement!" - When the Sentinels were going to appear.
 * "We need to go, right now." - To the Master Chief.
 * "Get us out of here!" - From Master Chief's helmet.
 * "Look out!" - When the Sentinels started to attack the Master Chief.
 * "We can't let the Monitor activate Halo. We have to stop him. We have to destroy Halo. According to my analyses of the available data, I believe the best course of action is somewhat... risky. An explosion of sufficient size will help destabilize the ring, and will cut through a number of primary systems. We need to trigger a detonation on a large scale, however. A star ship's fusion reactors going critical would do the job. I'm going to search what's left of the Covenant Battlenet, and see if I can locate the Pillar of Autumn's crash site. If the ship's fusion reactors are still relatively intact, we can use them to destroy Halo." - When the Master Chief is leaving the Control Room.
 * "I haven't located the crash site yet. We need to buy some time, in case the Monitor or his Sentinels find a way to activate Halo's final weapon without the Index. The machinery in these canyons are Halo's primary firing mechanisms. They consist of three Phase Pulse Generators that amplify Halo's signal, and allow it to fire deep into space. The power levels are enormous. I can't even begin to calculate the pulse's range. So, if we damage or destroy these generators, the Monitor will need to repair them before Halo can be used. That should buy us some time. I'm marking the location of the nearest Pulse generator with a nav point. We need to move in and neutralize the device." - When the Master Chief is leaving the Control Room facility.
 * "Wait. We should commandeer one of those Banshees; we'll need it to reach the pulse generator in time."
 * "Good, let's get moving. The nav point marks our target." - When the Master Chief grabbed a Banshee.
 * "That's the pulse generator. The center core is the signal amplifier. That's what we need to shut down. We need to interrupt the pulse generator's energy stream. I've adjusted your shield system so that it will deliver an EMP burst to disrupt the Generator. You will need to walk into the beam, to trigger it. The EMP blast should neutralize the generator. But it will also drain your shields, and you will be vulnerable until they recharge."
 * "Objective accomplished! The pulse generator has overloaded. Outstanding. The generator's central core is off line. Well done." - When the first pulse generator is destroyed.
 * "The second pulse generator is located in the adjacent canyon. Move out, and I'll mark the target with a nav point when we get closer."
 * "Head through that door. That's the way to the next canyon." - In the bridge structure.
 * "OK. Lets take care of the next pulse generator." - In the canyon with the next pulse generator.
 * "Wait! We haven't destroyed the pulse generator yet. Find a Banshee, and fly it up to the location marked by the nav point." - When you're flying to the tunnel, without destroying the second generator.
 * "That did it! The pulse generator overloaded. One more to go." - When the second pulse generator is destroyed.
 * "I've located the Pillar of Autumn. She put down twelve-hundred kilometers upspin. Energy readings show her fusion reactors are still powered up. The systems on the Pillar of Autumn have fail safes that even I can't override, without authorization from the Captain. We'll need to find him or his neural implants, to start the fusion core detonation. One target remaining. Lets take care of the final pulse generator." - When the Master Chief is leaving the facility with the second pulse generator.
 * "That tunnel leads to the next section of canyon. The final pulse generator we need to destroy is through there." - In the tunnel with the Covenant fighting against the Flood.
 * "Final target neutralized. Lets get out of here." - When the third and final pulse generator is destroyed.
 * "No, that'll take too long." - When the Master Chief is going to find a vehicle and get to the Captain Keyes.
 * "There's a teleportation grid that runs throughout Halo. That's how the Monitor moves about so quickly. I learned how to tap into the grid when I was in the Control Room. Unfortunately, each jump requires a rather consequential expenditure of energy."
 * "But I'm pretty sure I can take the needed energy from your suit without permanently damaging your shields. Needless to say, I think we should only try this once." - About teleportation.

Keyes

 * "The Covenant network is in absolute chaos! From what I've been able to piece together, their leadership ordered all ships to abandon Halo when they found the Flood, but they were too late. The Flood overwhelmed this cruiser and disabled it. The Covenant are terrified the Flood will repair the ship and use it to escape from Halo. They've sent in a strike team to kill the Flood and repair the ship for immediate departure. I've got a good lock on Captain Keyes' CNI transponder signal! He's alive! And the implants are intact! There's some interference from the cruiser's damaged reactor. I'll bring us in as close as I can."
 * "Ohh... I see! Coordinate data needs to be- " - When the Master Chief was teleported in upside down.
 * "Right. Sorry." - When the Master Chief hit a part of his helmet with his fist.
 * "Captain? Captain?! I've lost him." - After receiving a message from Captain Keyes, who wanted the Master Chief to leave him.
 * "Analyzing damage...This hole was caused by some kind of explosive. Very powerful if it tore through a ship's hull. All I detect down there are pools of coolant. We should continue our search somewhere else." - In a hangar with a large hole in the floor.
 * "Warning! Threat level increasing!"
 * "That jump into the coolant is looking better all the time, Chief!" - When the Flood is forcing the Master Chief into the hole.
 * "Trust me! It's deep enough to cushion our fall!"
 * "Chief, we need to jump now!" - When you're still refusing to jump to the hole.
 * "Let's get out of here, and find another way back aboard the ship." - When you're getting out of the pool of coolant.
 * "We should head this way, towards the ship's Gravity Lift." - In the canyon.
 * "The crash did more damage than I suspected. Analyzing. Coolant leakage rate is significant. The ship's reactor should already have gone critical." - In the area with another pool of coolant.
 * "Power source detected. There's the Gravity Lift. It's still operational! That's our way back in!" - When you've reached the Gravity Lift.
 * "We should be able to get into the ship's control room from here." - When the Master Chief is aboard again.
 * "The Covenant Battlenet is a mess. I can't access the ship's schematics. My records indicate that a shuttle bay should be... Here." - Marking the target with a nav point.
 * "Look, in the corners. The Flood are gathering bodies here." - In the large hangar.
 * "Looks like another shuttle bay. We should be able to reach the control room from the 3rd level."
 * "He's delirious! In pain! We have to find him!" - After second message from Captain Keyes.
 * "The control room should be... This way." - In the third level.
 * "The Captain! His vitals are fading! Please, Chief, hurry!" - After the last message from Captain Keyes.
 * "No human life-signs detected. The Captain! He's one of... them. We can't let the Flood get off this ring! You know what he'd expect... What he'd want us to do." - When the Master Chief found the Proto - Gravemind with Captain Keyes.
 * "It's done. I have the code. We should go. We need to get back to the Pillar of Autumn. Lets go back to the shuttle bay and find a ride." - When the Master Chief took the neural implance from Captain Keyes' head.
 * "Perfect. Grab one of the escort Banshees, and use it to return to the Pillar of Autumn."

The Maw

 * "This thing is falling apart!" - About damaged Banshee
 * "We're not gonna make it!" - To the Master Chief.
 * "Pull up! Pull up!"
 * "You did that on purpose, didn't you?" - When the Master Chief crashed the Banshee.
 * "We need to get to the bridge. From there, we can use the Captain's neural implants to initiate an overload of the ship's fusion engines. The explosion should damage enough systems below it to destroy the ring." - In the Pillar of Autumn's corridors.
 * "The bridge. We made it. Let's get to work."
 * "I need you to upload me into the control systems. The terminal is located next to the main viewscreen."
 * "I leave home for a few days, and look what happens. This won't take long." - When she appears from the terminal.
 * "There. That should give us enough time to make it to a lifeboat and put some distance between ourselves and Halo before the detonation." - Activating Self Destruct Sequence.
 * "Oh, hell." - Hearing 343 Guilty Spark.
 * "He's in my data arrays, a local tap!"
 * "He stopped the self-destruct sequence...."
 * "At least I still have control over the comm channels." - To the Master Chief.
 * I'm detecting taps throughout the ship, Sentinels most likely. As for the Monitor ... he's in Engineering. He must be trying to take the core offline! Even if I could get the countdown restarted ... I don't know what to do." - To the Master Chief.
 * "Not much. A well-placed grenade perhaps, but why?" - When the Chief asked her how much fire power is needed to crack engine's shield.
 * "Okay, I'm coming with you."
 * "Chief! Sentinels!"
 * "The ship was heavily damaged when it crashed. Head to the cyrochamber. We should be able to get to the engine room through there."
 * "Engine room located. We're here." - When you entered to the Engineering.
 * "Alert! The Monitor has disabled all command access. We can't restart the countdown. The only remaining option is to detonate the ship's fusion reactors. That should do enough damage to destroy Halo. Don't worry, I have access to all of the reactor schematics and procedures. I'll walk you through it. First, we need to pull back the exhaust couplings. That will expose a shaft that leads to the primary fusion drive core." - Instructing the Master Chief.
 * "Good! Step one complete! We have a straight shot into the fusion reactor! We need a catalyst explosion to destabilize the magnetic containment field surrounding the fusion cells. Use an explosive. I recommend a Grenade or a Rocket. If you run out of explosives, there is an armory station located near the engine room's entrance." - When the first manifold is opened.
 * "Analyzing. Fusion reactor number one destabilizing. Use explosives on the other three reactors. That should be enough to trigger a wildcat explosion of the engines." - When the first reactor is destroyed.
 * "Keep it up! Only one more fusion reactor to go!" - When the three reactors are destroyed.
 * "That did it! The engine's gone critical! Based on the current rate of decay, we should have fifteen minutes to get off the ship; we don't have much time! We should move outside and signal for evac. Accessing schematics . . . there's a service lift at the top of the engine room! It leads to a class 7 service corridor that runs along the ship's dorsal structure. Hurry!" - When the last reactor is destroyed.
 * "Cortana to Echo 419, come in Echo 419!" - In the elevator.
 * "The Pillar of Autumn's engines are going critical, Foe Hammer! Request immediate extraction! Approach the crash site and be ready to pick us up at external access junction 4C as soon as you get my signal!"
 * "Negative, negative! We have a wildcat destabilization of the ship's fusion core. The engines must have sustained more damage than we thought!" - When Foe Hammer asked her if everything is okay.
 * "Analyzing! We have six/five minutes before the fusion drives detonate. We need to evac NOW!" - To the Master Chief, on Legendary difficulty it will be five minutes.
 * "Activating final countdown timer. When it reaches zero, the engines will detonate. The explosion will generate a temperature of almost 100,000,000 degrees. Don't be there when it blows." - To the Master Chief, in the Warthog station.
 * "We won't make it like this, we'll need a vehicle!" - When you ignore the Warthog.
 * "Cortana to Echo 419! Request extraction now, on the double!" - To the Foe Hammer.
 * "Chief your going the wrong way we need to get of the ship." when the chief goes the wrong way.
 * "Wait, stop! This is where Foe Hammer is coming to pick us up. Hold position here." - To the Master Chief.
 * "Cortana to Echo 419! Two Covenant Banshees are approaching on your six! Evade, say again, evade!"
 * "Echo 419!" - When Foe Hammer is shot down.
 * "She's gone. Calculating alternate escape route. The ship's inventory shows one Longsword fighter still docked in Launch Bay 7. If we move NOW, we can make it!" - To the Master Chief.
 * "Chief, up ahead there's a gap in the trench! At top speed, we should be able to clear it!"
 * "That's the ship! Move, we need to get aboard NOW!" - In the bay.
 * "We're cutting it close!" - In the final cutscene, when the Master Chief reached the Longsword.
 * "Shut them down, we'll need them later." - When Longsword's engines were going critical, in the space, when Halo started to explode.
 * "Fancy a look?" - When Halo was exploding.
 * "Scanning... Just ... dust and echoes. We are all that's left." - When the Master Chief asked her, if anyone else UNSC member survived.
 * We did what we had to do! For Earth! An entire Covenant armada obliterated, and the Flood! We had no choice. Halo ... It's finished." - Her final words in Halo: Combat Evolved.

Cairo Station

 * "Another whisper, sir, near Io. We have probes en route." - To Terrence Hood.
 * "You look nice." - To the Master Chief.
 * "Slipspace ruptures directly off our battle cluster." - To Terrence Hood.
 * "Fifteen Covenant capital ships holding position just outside the kill zone."
 * "Gladly." - When Admiral Hood ordered her to use [MAC gun.
 * "Malta, what's your status, over?" - When Covenant boarders left the Malta Station.
 * "That explosion came from inside the Athens. Same as the Malta. The Covenant must have brought something with them. A bomb." - When the Athens Station exploded.
 * "Chief, we don't have much time!" - Pushing you to get to the Covenant Bomb.
 * "Not very much time on the clock, Chief!"
 * "Where are you? The bomb is right here!"
 * "Sir, boarders have breached the fire control center. They have a bomb." - To Lord Hood.
 * "Yes, but I'll need the Chief's help to make contact with the detonator." - To Lord Hood, about defusing the Covenant Bomb.
 * "Registering all hostile vessels inside the kill zone. Thirteen cruisers, two Assault carriers. I'm going loud!"
 * "The first carrier completely ignored us, Sir! Blew right through the Malta's debris field and headed straight for Earth!" - To Lord Hood.
 * "Just so you know, there are quite a few Elites guarding the bomb. You may need to get creative." - To the Master Chief.
 * "Me. Inside your head. Now." - When the Covenant forces quarding the Covenant Bomb are killed.
 * "You don't want to know." - When the Master Chief asked her how much time was left to the detonation.
 * "I know what you're thinking, and it's crazy." - When the Master Chief is going the Covenant Bomb against the Covenant.
 * "Unfortunately for us both ... I like crazy."
 * "Just one question. What if you miss?"

Outskirts

 * "The message just repeats. 'Regret, Regret, Regret.'" - By O.S.
 * "Regret is a name, Sergeant. The name of one of the Covenant's religious leaders. A Prophet. He's on that carrier, and he's calling for help." - By O.S., to Avery Johnson.

When the Pelican is crashed.
 * "You all right, Chief?" - On Easy.
 * "Hey, wake up." - On Normal.
 * "Talk to me, should I start CPR? What's going on?" - On Heroic.
 * "Blink, if you can hear me." - On Legendary.


 * "Hunters." - To the Master Chief, when the pair of Hunters appear.
 * "Second squad, this is Cortana. What's your status, over?" - When the Hunters are killed.
 * "Find a hole, stay put. We'll come to you." - To Gunnery Sergeant Pete Stacker.
 * "The highest concentration of Covenant ground troops is directly below the carrier. I don't think they want you to get on board." - To the Master Chief.
 * "Cut the chatter! We got trouble."
 * "This tunnel leads up to the bridge. It's full of rats if you know what I mean, but it beats swimming." - In the highway tunnel.
 * "I've been analyzing the Covenant tactical chatter. They're surprised, confused... I don't think they expected us to be here. Not... you and me...all of us... humanity, on Earth. Odd, I know, but it does help explain why they came here with such a small fleet."
 * "The Covenant must be trying to regroup. Don't let them." - To the Master Chief, when the group of Shadows appeared in the highway tunnel.

Metropolis

 * "Thanks for the tank. He never gets me anything." - To Avery Johnson.
 * "That's quite a welcome party." - When a group of Banshees appear.
 * "There are Marines trapped inside that building. Concentrate on the Wraiths, they're the biggest threat."
 * "There is a Marine Command - house in that building. We must help them deal with that Scarab." - To the Master Chief.
 * "Who's in charge now, Corporal? - By O.S., to Corporal Perez.
 * "It can't go any further this way. We have it trapped." - When the Scarab reached the end of the canal.
 * "Chief, we're going to have to board that Scarab."
 * "Careful Chief, that Elite was an Ultra, and those pilots are no pushovers either." - When you've killed an Ultra Elite in the Scarab.

Delta Halo

 * "We're fine." - When Avery Johnson asked Master Chief if he's alright, after In Amber Clad jumped out of slipspace.
 * "That... is another Halo." - To Miranda Keyes.
 * "It is. If activated, this ring will cause destruction on a galactic scale." - To Miranda Keyes, confirming that Halo is a weapon.
 * "Yes, ma'am." - To Miranda Keyes wanting the information about first Halo.
 * "Hang on to your helmet!" - To the Master Chief, before the pods are dropped.
 * "Could we possibly make any more noise?!" - When the pod landed on Delta Halo surface, the Master Chief kicked out the pods' cover.
 * "I guess so." - When the Master Chief grabbed a Rocket Launcher.
 * "Artillery disabled, Sergeant. Landing zone secure ... for the moment." - By O.S., to Avery Johnson.
 * "Easier said than done. Inbound Phantoms, Chief."
 * "Another Phantom, on approach!" - When troops from the first Phantom are killed.
 * "Hold here until the Pelican arrives, Chief."
 * "Here comes our ride." - When the Pelican appears.
 * "Let's wait here until our Warthog arrives ... unless you prefer to walk." - When you're not waiting for the Pelican and Warthog.
 * "I saw it too. It looks like a temple. If I were a megalomaniac, and I'm not, that's where I'd be." - To Avery Johnson, about facility in the lake.
 * "The Covenant have control of the bridge ahead. They're going to try to bottle us up on this side of the gorge. The controls to extend the bridge should be in this structure."
 * "Watch out, Chief! Wraiths on the far side!"
 * "Good, the bridge is down. Now about those Wraiths..." - By O.S., to Avery Johnson.
 * "A sermon, actually. I've been listening to it since we landed. So far, some standard Covenant literature, but I'll translate if he says anything interesting." - To the ODST Marine, about Prophet of Regret hologram.
 * "Regret's giving a speech, a sermon, to be exact. So far it's the standard Covenant liturgy but I'll translate If he says anything interesting." - To the Master Chief, about Prophet of Regret hologram.
 * "What? You don't want the tank? Ok, we'll leave it for the others." - When you ignore a Scorpion dropped by a Pelican.
 * "Careful. We're coming up to another structure." - While you're passing the ruins.
 * "Pelican, inbound! Lets clear a Landing Zone!"
 * "The Covenant are holed up in the middle of this structure. We need to clear them out."
 * "Transcendence, huh? More like mass-suicide." - Commenting to the Prophet of Regret hologram speech.
 * "You always brought us to such a nice places." - In the area with waterfall.
 * "Good, still no word about In Amber Clad on the Covenant battlenet. It's odd, the Covenant knew we made landfall, but they don't seem to consider us a very serious threat. Boy, are they in for a big surprise." - Near a temple.
 * "Watch yourself! Honor Guards!" - In the temple with another Prophet of Regret hologram.

Regret

 * "Wait, go back." - To the Master Chief, near the Prophet of Regret hologram.
 * "That's what I thought he said. The Prophet of Regret is planning to activate Halo!" - To the Master Chief.
 * "Pretty much" explaining regret's sermon to John
 * "[Master Chief|You]] know, I think the Forerunners built these new structures around the old, to protect them, to honor them. Pure speculation, mind you. I'd need to make a thorough survey to be sure." - To the Master Chief.
 * "Understood, ma'am." - To Miranda Keyes sending a few support.
 * "A Gondola's launching from the far towers. Big surprise, it's full of Covenant reinforcements." - To the Master Chief.
 * "Well, they were nice enough to bring us a ride." - After all Covenant forces in the first Gondola are killed.
 * "This Gondola won't get us all the way to the main temple, but it'll get us close. Let's get on board." - When you're waiting around the Gondola.
 * "If you hit the activation switch, it should drive itself."
 * "This lake couldn't have been created by volcanic action, which means it was either built this way on purpose, or was created by some other cataclysmic event. I'm sorry... were you trying to kill something?" - On the Gondola passing trough the lake.
 * "Ah, now I see. There's a submerged section that connects these towers to the outlying structures. Looks like we're going down. Unless you'd prefer to swim." - When you reach the underwater lift.
 * "All right, let's see where this elevator goes."
 * "I've intercepted a secure transmission from Regret's Carrier to the something called... High Charity. It seems to be a formal apology to the Prophets of Truth and Mercy. Apparently, Regret jumped the gun when he attacked Earth. He's asking the other Prophets to forgive his premature arrival, arguing that no human presence was foretold. That explains why there were so few ships in his fleet. But it's odd that a Prophet would have such bad intel about his enemy's homeworld." - In the underwater lift.
 * "And people say I'VE got a big head." - In the underwater chamber with huge hologram of the Prophet of Regret.
 * "Regret's carrier just received a response from High Charity. A very well encrypted message from the Prophet of Truth. Listen to this: Your haste has jeopardized the fulfillment of our Covenant, threatened our Grand Design. That you shall be spared a public display of our contempt is thanks only to Mercy and his wise counsel. Truth, Mercy, Regret. Three Prophet Hierarchs. Killing Regret should shake up the Covenant leadership. But frankly, it sounds like you might be doing Truth a favor."
 * "Great Journey? Doesn't he know what these rings do?" - Commenting the Prophet of Regret hologram speech.
 * "There. Another Gondola. Looks like it leads straight to the main temple. Not much further now." - To the Master Chief.
 * "So far, so good. We're approaching the main temple now." - O.S., to Miranda Keyes.
 * "That's the largest Covenant fleet I've ever seen ... the largest anyone's ever seen. Get inside the temple and kill Regret, before it can stop us!" - By the entrance to the main temple, after the Covenant fleet jumped out of slipspace.
 * "There's the target, take him out!" - To the Master Chief.
 * "His throne's shielding is protecting him. Get in close and do whatever you can."
 * "You've got to get him out of that throne."
 * "Quick, board his throne!"
 * "Bad news, Chief, the Phantoms are turning around. The fleet is preparing to fire on OUR position. We need to get out of here." - When the Prophet of Regret is killed.

Gravemind

 * "What ... is that?" - When the Master Chief wakes up being held by Gravemind.
 * "Brutes! The faster you can kill these Brutes, the better. They don't have shield generators, but take them out before ... It's berserking!" - In the High Council's chamber.
 * "Oh, I don't think so." - In response to Tartarus' announcement.
 * "Put me down on one of the pedestals near the door." - After Covenant forces in the chamber are killed.
 * "That Prophet... Truth, he has the Index. You've got to take it from him. Let me get these doors. Go! It will be easier to track Truth if I stay in the network. Don't worry. You can pick me up later."
 * "Watch out for the Captain, it's got a Brute Shot!" - On the ledge, where the Arbiter was marked by a Mark of Shame.
 * "Truth is moving through the lower levels of the tower. I'll reverse this gravlift. Drop down, try to cut him off. It's safe, really. Just step in." - When all the Covenant forces on the ledge are dead.
 * "After that stunt on the Cairo, I know you're not afraid of heights." - If you wait.
 * "Fine, I won't watch. Meet you at the bottom, okay?"
 * "They're beefing up their patrols. Stay sharp." - In the corridor.
 * "Wait a minute! I'm reading Marine IFF transponders. The signals are originating somewhere below your position."
 * "There's another lift in the next room."
 * "Here, Chief. Jump in." - When you reached the lift.
 * "There are two groups of Marines in this detention block. I'll zero their locations. You neutralize the guards. ... Quietly." - In the prison area.
 * "Come to the lower/middle level. The Marines are just inside, careful of the guards."
 * "Listen up, Marines! The Chief's hunting a Prophet, and you're gonna help him kill it." - When the first group of the Marines was set free.
 * "One more group of Marines to go, Chief."
 * "Come to the lower/middle level. More guards, get ready."
 * "That's all the Marines, Chief. Good work." - When the second group of the Marines is set free.
 * "We'll get out of here the same way we came in--the central gravlift."
 * "The lift is clear. Step on in." - When the reinforcements are killed.
 * "We've got to get after Truth, Chief. Step into the lift." - If you wait.
 * "Excellent! Truth is broadcasting on the move. It'll make him much easier to track." - When you went out of the lift.
 * "I've got a fix on Truth, just outside this tower, Chief. There's an exit nearby. Hurry."
 * "You wouldn't believe the number of kill-systems the Covenant are throwing down around me. Not to worry, it's pretty sloppy stuff. I guess they never expected a hostile intelligence to penetrate their networks from the inside."
 * "The Covenant just destroyed two of their own ships! And I'm hearing reports of small arms fire throughout their fleet." - After defeating a pair of Hunters.
 * "Slipspace rupture. It's In Amber Clad!" - Near the lift.
 * "Hailing ... No response. She's crashed into another tower ahead of our position. I'll keep trying to make contact, but I'm not registering any human vital signs."
 * "If we're going to catch Truth, we'll need to take a shortcut, straight through the Mausoleum. Look on the bright side, for now, they seem much more interested in killing each other." - In the way leading to the Mausoleum of the Arbiter.
 * "You might consider sitting this one out." - When you're entering the Mausoleum of the Arbiter.
 * "Hang on! I'm picking up two more transponders. It's the Commander and Johnson! They're closing on Truth's position, Chief. They'll need your help. This way, Chief."
 * "...This isn't good. I’m getting confirmed reports of Flood leaving In Amber Clad's wreckage. Let's get the Index and find a way out of here. Before things get really ugly." - The end of the level.

High Charity

 * "That structure at the center of the city! It's a Forerunner Ship... And Truth is heading straight for it! If he leads the Covenant fleet to Earth, they won't stand a chance. You have to stop him!" - Appearing on the Mercy's throne.
 * "If he does, I'll detonate In Amber Clad's reactor just like we did the Autumn's. The blast will destroy this city and the ring. Not a very original plan, but we know it'll work." - About a possibility of activating Installation 05 by Tartarus.
 * "No. I don't want to chance a remote detonation. I need to stay here." - When the Master Chief wanted to pick her.
 * "Flood controlled dropships are touching down all over the city! That creature beneath the Library... That 'Gravemind'... Used us. We were just a diversion. In Amber Clad was always its intended vector. There's a conduit connecting this tower to the ship. Head back inside. I'll lead you to it."
 * "We don't have time for this, Chief. Truth's Phantom is nearing the Forerunner Ship." - If you're fighting.
 * "I'll disable this lift once you reach the top. That'll slow them down... I hope." - When you're in the Gravity Lift.
 * "I'll do what I can to slow the launch sequence. There's something inside the ship... A presence that's fighting back! For a Covenant construct, it's unusually formidable."
 * "The security systems in this part of the tower are particularly robust."
 * "Apparently, these are the Prophet Hierarch's quarters. Their inner Sanctum." - When the Master Chief is near the Sanctum of the Hierarchs.
 * "Brute and Elite ships are engaging one another all around High Charity. I}'m running out of options, [[Master Chief|Chief! I can't stall the launch sequence much longer. The next lift will take you up to the conduit. Hurry!" - In the Sanctum of the Hierarchs.
 * "I knew the Covenant was good at re-purposing Forerunner technology, but this is amazing... They've been using the Forerunner ship's engines as an energy source for the city. The ship isn't so much launching as it is disengaging; uncoupling itself from High Charity's power grid. Stopping Truth, that's all that matters!"
 * "You know the plan. You've got to catch Truth, I've got to handle the Index. Go!" - When you're near the platform with the conduit leading to the Forerunner Ship.
 * "Forget about the Flood, you've got to get aboard!"
 * "I can't go with you!" - When you're on the platform but continue to wait.
 * "I have to stay here, Chief!"
 * "Chief, leave me!"
 * "We're out of time, Chief! Get on the conduit!"
 * "Jump in, now!"
 * "Chief, when you get to Earth, good luck." - When the Master Chief gets into the Forerunner Ship.
 * "Don't make a girl a promise... If you know you can't keep it..." - When the Master Chief promised her, he will back and rescue her.

Halo 3

 * "They let me pick, did I ever tell you that?... Choose whichever Spartan I wanted. You know me. I did my research. Watched as you became the soldier we needed you to be. Like the others, you were strong and swift and brave. A natural leader. But you had something they didn't. Something no one saw... but me. Can you guess? Luck. Was I wrong?" - Cortana's voice in the beginning of Arrival.
 * "Don't make a girl a promise ... if you know you can't keep it." - Recolling Cortana's words in Arrival.
 * "Could you sacrifice me to complete your mission? Could you watch me die?" - Cortana Moment in the level Sierra 117.
 * "You have been called upon to serve." - Cortana Moment in the level Crow's Nest.
 * "You will be the protectors of Earth and all her colonies." - Reffering to Catherine Elizabeth Halsey's words, Cortana moment in the level Crow's Nest.
 * "There will be a great deal of hardship on the road ahead." - Cortana Moment in the level Crow's Nest.
 * "You will become the best we can make you." - Cortana Moment in the level Crow's Nest.
 * "This place will become your home."
 * "This place will become your tomb." - Cortana Moment in the end of the level Crow's Nest.
 * "I have defied Gods and Demons..." - Cortana Moment in the level The Storm.
 * "I am your shield... I am your sword." - Cortana Moment in the level The Storm.
 * "This is the way the world ends..." - Cortana Moment in the level The Storm, after the UNSC Ships engaged the Forerunner Dreadnought and the Portal was activated.
 * "Chief. I can't tell you everything... It's not safe. The Gravemind... It knows I'm in the sys..." - Cortana Moment in the level Floodgate.
 * "Chief!" - Incomplete Cortana's message from the Covenant memory unit in the crashed Flood infested CCS-class Battlecruiser.
 * "High Charity, the Prophets' holy city, it's on its way..." - Incomplete Cortana's message.
 * "Chief!" - After 343 Guilty Spark repaired Cortana's hologram.
 * "High Charity... The Prophets' holy city, is on its way to Earth, with an army of Flood. I can't tell you everything. It's not safe. The Gravemind... It knows I'm in the system." - Cortana's message playing back on board of the Shadow of Intent.
 * "But it doesn't know about the Portal, where it leads. On the other side, there's a solution; a way to stop the Flood, without firing the remaining Halo rings." - Cortana's message.
 * "Hurry, Chief! The Ark... There isn't much time." - The end of Cortana's message.
 * "It asked, and I answered. For a moment of safety, I loosed damnation on the stars." - Cortana Moment in the level The Covenant.
 * "I'm a thief... but I keep what I steal." - Cortana Moment in the level The Covenant.
 * "A collection of lies; that's all I am! Stolen thoughts and memories!" - Cortana Moment in the level Cortana.
 * "It was the coin's fault! I wanted to make you strong, keep you safe. I'm sorry, I can't...
 * "May I speak with you, please? ... What's your name? It's very nice to meet you!... You like games? So do I." - Reffering to Catherine Elizabeth Halsey's words, Cortana Moment in the level Cortana.
 * "I'm just my Mother's shadow... don't look at me, don't listen! I'm not who I used to be..." - Cortana Moment in the level Cortana.
 * "I have walked the edge of the abyss. I have seen your future. And I have learned!" - Cortana Moment in the level Cortana.
 * "There will be no more sadness, no more anger, no more envy!" - Cortana Moment in the level Cortana.
 * "This is UNSC A.I. Serial Number CTN0452-9. I am a monument to all your sins." - Cortana Moment in the level Cortana.
 * "...you found me..." - When the Master Chief finds Cortana in the infected High Charity.
 * "But so much of me is wrong... out of place. You might be too late..."
 * "...you... keep it. I do know how to pick 'em."
 * "The Activation Index from the first Halo ring. A little souvenir I held onto... just in case. Got an escape plan?"
 * "Just keep your head down! ... There's two of us in here now, remember." - Reffering to Halo: Combat Evolved.
 * "Chief, get me out of this place. I... I don't want to stay." - If you delay going out of the room.
 * "Wait, we need to buy some time. This reactor... start a chain reaction. Destroy High Charity."
 * "You hurt it, Chief. But not for long. We need to get to Halo - destroy the Flood once and for all." - After destroying the reactors.
 * "An explosion just made us an exit! I'll mark it on your HUD, Chief, go!"
 * "Analyzing the route ahead ...I have it mostly figured out. Just keep moving, I'll update your HUD as you go."
 * "Corridors ahead have all collapsed. I'll find another way, Chief; be careful."
 * "There, Chief, into the maintenence tunnel."
 * "I've got a friendly contact! But who would be crazy enough to come in here?" - When the Arbiter's signal appears in the Motion Tracker.
 * "Wait, you two made nice?! What else have you been up to...?" - When she saw the Arbiter.
 * "Johnson? Do you have the Frigate?" - In the beginning of the level Halo.
 * "Safe is better than close, Sergeant Major."
 * "Halo. It's so new... Uunfinished. I'm not exactly sure what will happen when we fire it."
 * "Head through the cliffs."
 * "The Control Room isn't far!"
 * "Where are you going?" - When you're going to the Terminal.
 * "Wait, what's that?" - When you reached the Terminal.
 * "How many of these have you found?"
 * "Come on, Chief, let's get back on track. The Control Room is outside!"
 * "Flood Dispersal Pods! The Control Room's at the top of that tower Chief, go!"
 * "There should be ramps that lead to the top - check the other side!"
 * "Was that the Monitor? You didn't tell me he was here. Well, we are finally doing what he wanted." - After Avery Johnson's conversation with 343 Guilty Spark.
 * "Not for long. I'm tracking additional Dispersal Pods. They'll be hitting any minute!" - To Avery Johnson, by COM.
 * "It's trying to rebuild itself on this ring!"
 * "Yank me, Chief." - After reaching the Control Room.
 * "Chief... I'm so sorry." - After Johnson's death.
 * "The Dawn. Of course - the Frigate! We still have a chance!" - After second Installation 04 was fired.
 * "Find the doorway in the cliffs, Chief. The Dawn is on the other side."
 * "Don't let this ring be the end of us, Chief."
 * "There! Johnson's Warthog."
 * "Come on, Spartan - go, go, go!"
 * "Drive, Chief. Head for the Frigate."
 * "The Dawn is close. We can make it! As long as the ground doesn't fall out from beneath us..."
 * "The charging sequence - it's too much for the ring to take!"
 * "Halo is ripping itself apart!"
 * "Hurry, Chief! Don't stop! Charging sequence at 30%..."
 * "Come on! Faster!"
 * "50%, Chief!"
 * "70%!"
 * "80% charged."
 * "90% - firing sequence initiated!"
 * "Gun it, Chief!! Jump!! Floor it, right into the hangar!!" - Near the Forward Unto Dawn.
 * "Hang on!" - On the Forward Unto Dawn.
 * "Chief!!" - When the Warthog hits the Master Chief.
 * "If we don't make it--"
 * "It's been an honor serving with you, John."
 * "Chief?! Can you hear me?" - In the half of Forward Unto Dawn's wreck, drifting in the space.
 * "I thought I lost you, too."
 * "I'm not sure. When Halo fired, it shook itself to pieces. Did a number on the Ark. The Portal couldn't sustain itself. We made it through just as it collapsed."
 * "Well… some of us made it."
 * "But you did it. Truth and the Covenant... The Flood... It's finished."
 * "I'll drop a beacon. But it'll be a while before anyone finds us. Years, even."
 * "I'll miss you." - To John 117, closing himslelf in the Cryotube.
