Assault on the Control Room

Assault on the Control Room is the fifth and longest campaign level in Halo: Combat Evolved and Halo: Combat Evolved Anniversary. It is the first and only level the player can utilize a Scorpion tank, and the first level the Ghosts and Wraiths are seen in action.

In Halo: Combat Evolved Anniversary, upon completion of this level on any difficulty rewards the player the achievement "Assault on the Control Room", worth 25 Gamerscore points. Players who managed to destroy 4 of the Wraiths in this level are awarded by the achievement "Wraith Hunter" and 10 Gamerscore points. Additionally, players who managed to commandeer one of the Banshees in this level receive the achievement "I'll Be Taking That!", which is worth 25 Gamerscore points.

In Halo: The Master Chief Collection, completing the level on any difficulty unlocks the "Assault on the Control Room" achievement worth 10 gamerpoints. "Wraith Hunter" is unlockable with the same criteria and is worth 10 gamerpoints. "I'll Be Taking That!" does not return, though the player nevertheless must commandeer a Banshee to find the Siege of Madrigal music cue and unlock the "Madrigal Debut" achievement worth 5 gamerpoints. Beating the level's par time and par score will unlock the "Would It've Killed You To Take The Elevator" and "Vetro Strike" achievements respectively, each worth 10 gamerpoints. Activating the Terminal found on the level will unlock the "Hitchhikers May Be Escaping Convicts" achievement worth 5 gamerpoints, while finding the Fog and Malfunction Skulls will unlock the "Skulltaker Halo: CE: Fog" and "Skulltaker Halo: CE: Malfunction" achievements, each worth 5 gamerpoints.

Plot
The level follows the Master Chief on a mission to reach Halo's Control Room. The Covenant are deployed in greater numbers and in a more superior force than previously seen in the game, using Wraiths, Ghosts and Banshees. The majority of the level is set in a snowy, outdoor environment. Although the level seems to be natural, there are networks of tunnels and elevators built by the Forerunner that connect sections of the constructs into the Control Room.

The level is known for its variety and well roundness. It allows the player to use every weapon and vehicle in the game (except the Shotgun), and is the only level in Halo: Combat Evolved that allows the Master Chief to use a Scorpion tank. Although the level is famous for its snowy outdoor battles and large bridges, there are also a variety of indoor skirmishes, including standoffs with Sangheili Zealots. There is a mix of vehicle, long-range, and close quarters combat. The player is assisted by a handful of Marines after their Pelican crashes, but the level is mostly a solitary experience.

At the end, the Master Chief reaches the Control Room and Cortana interfaces with the computers. She is horrified to learn that Halo houses the Flood, and the weapons cache that Captain Keyes is looking for will lead him straight to the parasite. Cortana elects to stay behind, while the Chief rushes off to find the Captain.

I Would Have Been Your Daddy...
{Original Cutscene} {Anniversary Cutscene}



''Fade in to the interior of a large Forerunner dome. Pan down to a long shaft. A single Unggoy Minor paces on an open platform.''

''Close up of the walking Unggoy. Other Unggoy are sleeping nearby. He stops as he hears jets, he sniffs the air, and yelps as a Pelican rises up from the chasm in front of him, screams and runs towards the door.''

{Gameplay}


 * Carol "Foehammer" Rawley (COM): "This is as far as I can go!"


 * Cortana (COM): "Roger that. We can find our way to the Control Center from here."


 * Rawley (COM): "Good luck. Foehammer out."

''The Pelican hovers at the edge of the platform, the Chief gets out. He proceeds into a series of circular rooms and begins clearing them of Covenant.''


 * Cortana: "The Covenant presence here is stronger than I anticipated. They seem to have the entire region secured."

''The Chief emerges onto a bridge, where he discovers that it is snowing. On legendary a Banshee fighter flies around the area.''


 * Cortana: "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."

''A Pelican dropship flies over the bridge. The Covenant forces on the bridge (including the Banshee on legendary) open fire at it.''




 * Fire Team Zulu Sergeant (COM): "This is Fire Team Zulu requesting immediate assistance from any UNSC forces. Does anyone copy? Over."


 * Cortana: "I didn't think there were any human forces left on this part of the ring."


 * Cortana (COM): "Cortana to Fire Team Zulu, I read you. Fire Team Zulu, this is Cortana. Hold position. We're on our way."


 * Fire Team Zulu Sergeant (COM): "Roger that. Make it quick."

The Pelican descends to the area below the bridge.

''A Sangheili Zealot runs out of a door at the opposite side of the bridge and awaits the Chief, supported by a lance of Unggoy. The Chief kills them all and enters another structure and descends to the ground level, where he returns to the canyon. A large number of Covenant have three Marines with an overturned Warthog cornered. More dead Marines lie nearby. A Covenant Wraith tank fires plasma mortars as Shade turrets and Ghost vehicles strafe the marines.''


 * Marine #1: "Glad you could join the party, sir!"

or


 * Marine #2: "Master Chief, Sir! Good to see you!"

The Chief assists and they eliminate all of the enemies in the area


 * Marine #1: "They gave it their best shot, but they didn't count on running into the biggest squad of Marine bad-asses in the Corps!"

or


 * Marine #2: "That's all of them. The area's secure."



''The Chief finds a second group of Marines fighting near a Scorpion tank. With his assistance they clear the area.''


 * Marine #1: "Enemy forces eliminated. The area's secure."

or


 * Fire Team Zulu Sergeant: "That's the last of 'em - area secure. Stand down, team! They did their damnedest, that's for sure. This is all that's left of my platoon! The Covenant are down here in force... and they brought plenty of toys! I wouldn't have given us a snowball's chance until you showed up, Chief."

The Chief and the Marines advance.


 * Marine #3: "Aw, crap. Let's get the hell outta here, man! Somebody call the dropship!"


 * Fire Team Zulu Sergeant: "You stow that garbage right now, mister. You're a Marine, so act like it, dammit! We've got a job to do here."

or


 * Marine #2: "Shut up! Show some backbone, amigo. We're all in this together!"


 * Cortana (COM): "Negative, team. No evac available at this time. But the Chief and I could use some assistance."


 * Fire Team Zulu Sergeant: "Okay, Marines. Time to pay back the Chief for pulling your sorry tails out of the fire. Prepare to move out!"



''The Chief reaches a second large open area, where one Wraith hovers on the ice and another lurks on top of the cliff at the far end of the canyon. More Ghosts, Shades and Covenant infantry are also present.''

or or or
 * Marine #1: "Enemy mortar tanks sighted at my position... it's gonna be a busy day."
 * Marine #2: "Dang, they got armor support! Watch out for those tanks!"
 * Marine #3: "Bloody hell! Enemy forces have armor support... It's time to earn our pay."
 * Marine #4: "Contact, contact! Covenant mortar tanks are moving in!"


 * Cortana: "The Covenant placed their tanks to defend the entrance to the tunnel."

The Chief destroys the first Wraith tank.


 * Marine #1: "Looks like that armor wasn't so tough after all! Let's mop up the rest of 'em!"

''The Chief enters the tunnel, killing a pair of Mgalekgolo and comes across a large cavern. More Covenant wait inside, including another Mgalekgolo pair.''

or or or
 * Marine #1: "More Covenant sighted! Man, these guys are like cockroaches!"
 * Marine #2: "Contact, more Covenant sighted!"
 * Marine #3: "Aw man, more Covenant!"
 * Marine #4: "More Covenant!"

The Chief crosses the cavern and exits into another tunnel, which soon turns into a rocky slope heading upwards.

Rolling Thunder
The Chief clears the area of Covenant, including another Wraith and two Mgalekgolo.


 * Fire Team Zulu Sergeant: "You monkeys almost look like golden boys!"


 * Marine: "Damn straight!"

The Chief comes across two more Mgalekgolo chasing after a squad of Marines and Sergeant Stacker, where the path switches back and goes down to a frozen river leading to the cave to the last area of the second chasm.


 * Cortana: "I thought the Covenant had eliminated all the Marine forces in this area."

After the Chief engages and defeats the Mgalekgolo, a Covenant Spirit appears from behind the cliffs and drops in on the ridge he just descended from.

or or
 * Marine #1: "*Whispers* Hey, Anybody else hear that? Aw, man... Covenant dropship inbound, take cover!"
 * Gunnery Sergeant Stacker: "Look sharp, boys! Covenant dropship inbound, let's move!"
 * Marine #4: "Quiet... Anybody hear something? Covenant! Covenant dropship inbound!"


 * Marine #3: "The Covenant are dropping in behind us! We're trapped!"



The Chief nears some switchbacks leading up to final area of the second chasm.

or or
 * Marine #2: "Master Chief, the Covenant have stationary guns dug up in those rocks!"
 * Marine #3: "Whoa, sir! The Covenant are dug up in those rocks! They've got us pinned down here!"
 * Marine #4: "Covenant Forces are diggin' in those rocks sir, we can't move."


 * Cortana: "We need to get up this ridge."


 * Cortana (COM): "Marines, hold your positions. We'll handle those guns."


 * Cortana: "Master Chief, we should scale the ridge and get below those stationary guns."

or or
 * Marine #2: "Roger that. Marines, stay here and cover the Master Chief."
 * Marine #3: "I'm in no hurry for a heroic charge on those guns, Cortana. Holding position."
 * Marine #4: "Holding position. Everybody, keep your eyes peeled and cover the Master Chief."

They eliminates all enemies in the area, including a Banshee fighter and two Ghosts, and approach a door in the cliffs.


 * Cortana (COM): "Cortana to 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."

or or or
 * Marine #1: "That's affirmative! Fire Team Zulu out!"
 * Marine #2: "Affirmative! Okay people, evac bird's on the way!"
 * Marine #3: "Give 'em hell, sir! Fire Team Zulu out!"
 * Marine #4: "Roger, good luck."

The Chief battles his way through more interior areas and across two more bridges.


 * Cortana: "Resistance appears to be increasing. We must be close to the Control Center."

The Chief kills a pair of Mgalekgolo and a mixed group of Unggoy and Kig-Yar and finds another door.

If I Had a Super Weapon...
''The Chief reaches a door to the third chasm. Covenant infantry patrols the rock bridge he is on, and a massive structure can be seen on his left.''


 * Cortana: "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."

The Chief fights through the bridge and another indoor area before reaching the valley's bottom.


 * Cortana: "The entrance to the control room is at the top of the pyramid. Let's get up there. We should commandeer one of those Ghosts, we're going to need the firepower."

The Chief battles his way up the pyramid and through big doors into a large corridor, where he kills all of the Covenant inside, including a Sangheili Zealot.


 * Cortana: "Scanning... Covenant forces in the vicinity have been eliminated. Let's move on to Halo's Control Room."

The Chief opens the final door.

{Original Cutscene} {Anniversary Cutscene}




 * Cortana: "This is it. Halo's control center."

''The Master Chief walks through the door and to a control panel at the center of a circular glass walkway projecting into the middle of a massive open chamber. A holographic map of Halo surrounds a smaller holographic map of the system, which shows Basis and Threshold, and Halo itself between them. Also noticeable are the red areas shown on the lands of Halo, possibly indicating where the Flood is currently spreading.''


 * Cortana: "That terminal, try there."

''The Chief unplugs Cortana's chip from his helmet and places her chip in the terminal. A moment later, she appears above the display (In the original, data streams out from her in all directions, her eyes are now red and her body is green, shifting occasionally to blues/purples).''


 * Master Chief Petty Officer John-117: "You all right?"


 * Cortana: "Never been better! You can't imagine the wealth of information. The knowledge! So much! So fast! It's glorious!"


 * John-117: "So, what sort of weapon is it?"


 * Cortana: "What are you talking about?"


 * John-117: "Let's stay focused. Halo... how do we use it against the Covenant?"


 * Cortana: "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!"


 * John-117: "Slow down. You're losing me."


 * Cortana: "The Covenant found something, buried in this ring, something horrible, and now... they're afraid."


 * John-117: "Something buried? Where?"


 * Cortana: "The Captain, we've got to stop the Captain!"


 * John-117: "Keyes? What do we-"


 * Cortana: "The weapons cache he's looking for. It's not really- We can't let him get inside!"


 * John-117: "I don't understan-"


 * Cortana: "There's no time. Get out of here, find Keyes, stop him! Before it's too late!"

The Chief turns and runs from the Control Room.

Level ends.

Glitches

 * At the very beginning of the level, "Press X/E to enter side seat of Pelican" will appear. The player will be placed back on the Pelican as it flies back the way it came and can get off at any time. However, if the player doesn't get out the Pelican, it will crash and the player will die. This is known as the Pelican Death Glitch.
 * By jumping at the right point, it is possible to board Fire Team Zulu's Pelican. It flies down, drops off the Warthog, then flies along the canyon. It crashes near to but not right on top of the preexisting Pelican wreck.
 * When Fire Team Zulu's Pelican flies by the bridge, the vehicle's shadow is also seen on the lower part of the bridge.
 * On the original Xbox version, it was possible to take a Banshee after where the player can first get in the tank. This glitch doesn't work on the Xbox 360, most likely due to Bungie patching the glitch.
 * Any Covenant, except for the Mgalekgolo and Banshees, left alive near the Control Room will instantly die when the cutscene is triggered.
 * If the player brings a Banshee into the control room and kill him/herself and destroy the Banshee by using the Fuel Rod on the Banshee, the player will still move on to the cutscene, and the Banshee will be blue.
 * If player rides a banshee with full speed before the cutscene is triggered, there's a chance that the player will die when the cutscene begins. The cutscene will still carry on but the player can see that the Master Chief is dead or frozen, as result of the glitch running over by the Banshee when the cutscene is triggered.

Easter eggs

 * The Three dead Grunts Easter Egg are found on this level.
 * The song called Siege of Madrigal can be found at the end of this level. It can be found by flying a Banshee on the second bracket above the Control Room. Land the Banshee on the bracket and walk to the right until you reach the edge. Wait a few seconds and the song will start playing. It can also be found at the beginning if you fly a Banshee down the big shaft and stand on the right spot on the ledges.
 * In Anniversary, the Fog skull can be found on a raised platform in the center of the room after crossing the first bridge and taking the elevator to ground floor. The Malfunction skull can be found in the first underground chasm area, on one of the pipes sticking out and dropping to the chasm's bottom.
 * The fifth Terminal in Anniversary can be found in the hole at the end of the Control Room's giant beam, right under the beam and beside a few Marines' corpses.

Mistakes

 * In The Art of Halo the level is mistakenly called "Attack on the Two Control Rooms." However, this may have been an early name for the level.
 * The Pelican wreckage near the second group of marines from Fire Team Zulu uses Echo 419's model and numbers.
 * If the player crosses the bridge in the cavern in a Scorpion tank the glass can be heard breaking, even though the glass on the bridge is unbreakable.
 * Unggoy sleeping in the level will still say their lines (e.g. "He's unstoppable!") when killed silently by melee. Their cries will not alert the other AI characters of the player's presence. This glitch also happens on other levels.

Miscellaneous

 * The level description describes it as a defensive mission, while an assault is the opposite of it. Rather than staying in one place to fend off enemies, the player is the assault.
 * The "Lost Song", which was accidentally left out of the Halo: Original Soundtrack, is played on this level in the series of rooms where the player fights a group of Stealth Sangheili and a pair of Mgalekgolo, immediately before the rock bridge overlooking the Control Room.
 * This level features the largest amount of Mgalekgolo in a campaign level in the Halo Trilogy, a total of 16.
