ONI: Sword Base

ONI: Sword Base is the third level in the campaign of Halo: Reach. Upon completing this level on Normal, Heroic, or Legendary the player will unlock the "Protocol Dictates Action" Achievement and 10 Gamerscore.

Plot
The level begins on July 26, 2552 near Sword Base, an Office of Naval Intelligence research facility. The facility is located on the Babd Catha Ice Shelf in Eposz, near one of the poles of the planet. Noble Team is deployed to Sword Base after a Covenant corvette begins attacking the facility. Due to the sensitive nature of the facility, orbital MAC rounds are prohibited, forcing Noble Team to go groundside to defend the facility.

Two Falcons drop Noble Team around Sword Base. After Kat and Noble Six clear the courtyard outside the facility, they are ordered by Sword Control to proceed to the main gate. After Six eliminates two Wraiths outside the gate, a Pelican drops off a Warthog, which Kat and Noble Six ride to reactivate a COM array at Farragut Station to contact Command and an anti-air gun at Airview Base to help clear the skies. After completing their task, they meet up with the rest of the team at Sword Base. They fight their way up through the atrium to the top floor, where Noble Six assists Emile in driving off several Phantoms and Banshees. A pair of Longswords are then able to push through and chase off the corvette. As the corvette distances itself from Sword Base and begins to climb, the Longswords break off and the corvette is brought down by a slug from an Orbital Defense Platform.

Noble Team is called back into Sword Base by Dr. Halsey, who reprimands Carter for not pursuing the Sangheili Zealots at the Visegrad Relay. She explains that the Sangheili were most likely part of an artifact retrieval strike team, and that the notes stored at the Visegrad Relay held very important information. Kat then hands over the data module she retrieved from the station. Carter and Halsey exchange barbs, and Noble Team leaves as Dr. Halsey examines the data module.

Sword Base, Babd Catha Ice Shelf, Eposz

July 26, 2552, 11:26 Hours


 * Sword Control (COM): "Be advised, Kilo-33 and Kilo-34, your current LZ is too hot!"


 * Carter-A259: "Roger that. Dot, standby to receive and respond."

''The Falcons pass a large island. A Covenant Corvette holding position comes into view.''


 * Auntie Dot (COM): "Yes, Commander... coordinates received. Initiate immediate course correction. The Office of Naval Intelligence Sword Base is presently under siege from a corvette-class Covenant vessel. Due to the sensitive nature of this facility, use of orbital rounds has been, for the moment, prohibited. Regrettably, my efforts to obtain relevant data on enemy forces have been unsuccessful. However, current defensive forces are insufficient. ONI has requested Team Noble's direct intervention to help secure Sword Base."


 * Carter-A259: "All right people, we're stuck with that ship for the time being. Let's focus on the hostile infantry - give those troopers a hand."

A base security camera shows Covenant ground forces engaging UNSC Army troopers, as the Falcons fly overhead.


 * Carter-A259: "Kat, Six - you're out here. Jorge, Emile - you're next, get prepped."


 * Catherine-B320: "Let's move, lieutenant."

''The Falcon lowers close to the ground. Kat and Six jump out.''

{Gameplay}

The Best Defense...

 * Carter-A259 (COM): "Kat, Six: push back the attack on Sword Base, find out what we're dealing with."


 * Catherine-B320: "Roger that, we're your strike team."

Kat, Six, and a few troopers engage and eliminate some Covenant troops on an upper walkway.


 * Sword Control (COM): "Spartans, hostiles north."

The two Spartans head north to a courtyard, where they engage a significant number of Covenant troops, including several Elites.


 * Catherine-B320: "Let's knock some heads, Lieutenant!"


 * Sword Control (COM): "You've got enemy contacts, Spartans."

After clearing the courtyard, the Spartans head down a ramp where they engage several Skirmishers, eventually making it down to a gate.


 * Catherine-B320: "Noble Two to Sword Control: courtyard is clear, over."


 * Sword Control (COM): "Head to the main gate to the east, I'll brief you as you go."

The two Spartans enter the main gate, coming across several ordnance packs.


 * Catherine-B320: "Sword Control, I see a Target Locator. Any artillery support in the area?"


 * Sword Control (COM): "Limited, but we'll prioritize whatever you need, ma'am."

Get the Hell Off My Lawn!
''Noble Six takes the Target Locator, and the Spartans then head out of the base. The Covenant Corvette opens fire on the base. A damaged M831 Troop Transport is seen attempting to escape from two enemy Wraiths.''


 * 3 Echo 57 (COM):"3 Echo 57 heading back to base, we got enemy tangos on our six. How copy?"

The Warthog is soon destroyed by one of the Wraiths.

Using the Target Locator, Noble Six calls in artillery to destroy the two Wraiths.


 * Catherine-B320: "Outstanding!"


 * Catherine-B320: "Pelican inbound with transport, Six."

A Pelican is seen coming towards them with a Warthog.


 * Sword Control (COM): "The old Farragut Station has its own comms array that should bring back online with command. Airview Base has an anti-air battery that will help clear the skies."


 * Catherine-B320: "AA gun is to the west, comms array to the east. Let's roll."

If Noble Six heads west:


 * Catherine-B320: "I agree, go for the gun."

If Noble Six heads east:


 * Catherine-B320: "Good call. Let's get comms first."

After heading further west, they are engaged by Covenant forces, soon eliminating them.


 * Catherine-B320: "I'm picking up a power source, we're close to the AA gun."

''They arrive at the base, to find it under Covenant control. A Sangheili General with a Plasma Launcher commands the Covenant group.''


 * Trooper: "Contacts!"


 * Catherine-B320: "That's the gun over there. Should be a reset control somewhere, get it online."

''After eliminating the Covenant in the area, Noble Six heads into the two-floored building next to the AA gun. He or she finds the reset control on the roof of the building, and activates it. The AA gun immediately opens fire on the Banshees and Covenant dropships around the Corvette.''


 * Catherine-B320: "That did it, Six. AA gun is online."

If the comms array has not yet been activated:
 * Sword Control (COM): "Nice work, Spartans. Get to Farragut Station and get that comms array up and running."

A Pelican delivers a Warthog, facing the direction the Spartans must go to next.


 * Sword Control (COM): "Spartans, this is Sword Control. Thought you could use some mobile firepower."


 * Catherine-B320: "Always. Take that Hog, Six.

The Spartans head toward the comms array, encountering various Covenant troops, mostly infanty.


 * Catherine-B320: "We need to get that comms array online."

The Spartans soon arrive at the station.


 * Catherine-B320: "Hope that comms array has a working generator."

The station is also occupied by Covenant forces, including a Revenant.


 * Catherine-B320: "Let's search the area for a generator switch."

Noble Six searches the buildings, eventually finding the switch, and activates the generator.


 * Catherine-B320: "Okay, generator is up and running. Find that comms array, should be up high."

''A Spirit moves in and drops off a group of Skirmishers and Grunts to prevent Six from reaching the comms array. Six and Kat eliminate them. Noble Six soon finds the comms array in an adjacent building and activates it.''

Minimum Safe Distance

 * Carter-A259 (COM): "Noble Strike, this is Noble Leader. Get back to Sword Base ASAP."


 * Catherine-B320: "On our way, Commander. Six, let's go."


 * Sword Control (COM): "Good work, Spartans. Return to Sword Base, the rest of your team is inbound, imminent."

If both objectives have been achieved, a Gauss Warthog will be dropped by Pelican for the return trip to Sword Base.


 * Carter-A259 (COM): "Noble, be advised: Covenant Corvette moving into position. Kat, Six, get here quick. We need you inside."

The Spartans arrive at the gate, to find it under attack by several Revenants and a small group of infantry, which are subsequently eliminated.


 * Jun-A266 (COM): "We're stalled in the tower atrium. Kat, where are you?"


 * Catherine-B320: "Opening the gate now."

Once inside, Kat and Six head back up the courtyard, which is once again occupied by the Covenant.

''After clearing the courtyard, they find a few troopers besieged in the nearby garage by more Covenant troops, including a Hunter pair. Kat and Noble Six engage the Hunters and other Covenant troops and neutralize them.''


 * Catherine-B320: "Let's get to the atrium. We have to go through the elevator, Lieutenant. Take it."

''Noble Six activates the elevator to take them to the security office. Midway up, an explosion rocks the elevator.''


 * Emile-A239 (COM): "Corvette's hitting this base hard."


 * Catherine-B320: "Where's our orbital support? Got to be four platforms that could take it out with a single MAC round."

Office of Naval Intelligence
The elevator soon reaches the security office, Kat and Noble Six are immediately engaged by Covenant forces.


 * Sword Base Automated PA: "Welcome to the Office of Naval Intelligence. An ONI representative will meet you shortly."


 * Catherine-B320: "I doubt that very much."


 * Sword Base Automated PA: "Thank you, Lieutenant. You have been cleared for access."

Kat and Six soon move into a multi-level room, where Carter, Jun, and Jorge are engaging Covenant troops.


 * Jorge-052: "Hold it, everybody move up!"

If Noble Six's gender is:
 * (male)Carter-A259: "Six, head upstairs and assist Emile. Jorge, make sure he gets there."
 * (female)Carter-A259: "Six, head upstairs and assist Emile. Jorge, make sure she gets there."


 * Jorge-052: "Depend on it!"

Six and Jorge make their way upstairs, engaging various Covenant forces as they go, including another Sangheili General with a Fuel Rod Gun.


 * Sword Control (COM): "Corvette's gonna rip this base apart! What's the situation, Noble?"


 * Emile-A239 (COM): "Can't do this on my own! Need another Spartan up here!"


 * Carter-A259: "Six, get to the top floor and assist Emile."

Jorge and Six make it up to the top floor, which is in ruins.


 * Sword Control (COM): "Commander, this base won't survive another salvo from that corvette. Kill those Banshees!"


 * Carter-A259: "Upstairs, Lieutenant, we need those Longswords in the air."

''Six goes through a doorway to the top floor, where there is a massive hole in the building. The Covenant corvette is holding position just outside.''


 * Emile-A239: "About time."

Noble Four, Five, Six, and some Army troopers engage several Banshees, and a Phantom dropship, which drops off a pair of Stealth Elites.


 * Emile-A239: "Good shootin', Noble Six, watch down low."


 * Emile-A239: "Are you havin' fun yet?"

The Covenant air and ground troops are soon eliminated.


 * Emile-A239: "Yeah, clear. That's the way we get it done, Spartan! Clear."


 * Sword Control (COM): "Noble Team, Longswords are inbound and ready to push. Orbital defenses standing by to take the shot."

{Cutscene}

''Two Longswords fly towards the corvette, which is attempting to flee. Noble Six watches as the Longswords follow the corvette for a distance, but soon break off. A Super MAC round suddenly streaks down from the sky above and smashes right through the corvette. Its engines flicker, and it loses altitude. The view changes to Six. Jorge emerges from the shadows, approaching Six.''


 * Jorge-052: "Beautiful, ain't it? Someone should take a picture."

''The corvette crashes into the lake. Jorge gives Six a congratulatory pat on the shoulder.''


 * Jorge-052: "Nice work, by the way."


 * Noble Six: "I aim to please."


 * Carter-A259 (COM): "Five, Six...get down to the science wing. Doctor Halsey wants a debrief, and Command's saying we're all hers."


 * Jorge-052: "Repeat? Sounded like you said 'Halsey.'"


 * Carter-A259 (COM): "I did."


 * Jorge-052: "Copy that, on our way. Don't need Command to tell me... Been all hers half my life."

''Jorge and Six walk away, back into the base. The Corvette is shown in the background sinking into the lake.''

They soon arrive at the science wing, where Carter is talking to Dr. Catherine Halsey, who is behind a glass wall, separating Noble Team from her.


 * Halsey: "I requested your assistance, Commander, and do not need a report on events that occur on my own doorstep. What I do require is a detailed account of your previous engagement-"

Halsey pauses mid-sentence as she notices Jorge and Six enter the room.


 * Halsey: "Jorge. It's been too long."


 * Jorge-052: "Ma'am."


 * Halsey: "What have you done with my armor?"

Jorge and Noble Six look at Jorge's armor, which has been customized, just like the armor of the rest of Noble Team.


 * Jorge-052: "Just some... additions I've made."


 * Halsey: "Indeed. Visegrad Relay. Its data center was home to one of my xeno-archaeologists, Professor Laszlo Sorvad. Perhaps you could shed some light on his death."


 * Carter-A259: "If he was a civilian male in his mid-sixties, he died with a Covenant Energy Sword through his abdomen."


 * Halsey: "Elites, then."


 * Jorge-052: "They engaged us as well. It was just, uh, just after we found your scientist's daughter, ma'am. She was hiding in the-"


 * Halsey: "Irrelevant. The Elites. Tell me more about them."


 * Jorge-052: "Three. Zealot-class. One got by us. The leader, from the looks of him."


 * Halsey: "Zealots? You're certain?"


 * Jorge-052: "Their armor configuration matched."


 * Noble Six: "Shield strength, too."


 * Carter-A259: "I gave the order not to pursue. Our primary objective was to get the station's relay back online."


 * Halsey: "Your primary objective? Commander, are you a puppet or a Spartan?"

Emile and Jun look up at Dr. Halsey, indignant.


 * Carter-A259: "Ma'am?"


 * Halsey: "There are those at ONI, myself included, who believe the Covenant dispatch Elite advance teams to hunt down artifacts of value to their religion. Survivor accounts suggest such teams are small, nimble, and almost always Zealot-class. No doubt they came to the station for the abundance of ONI excavation data stored there. And you let them get away."


 * Carter-A259: "Data retrieval was not a command directive. Even had we known, we had other, more urgent matters to attend to."


 * Catherine-B320: "Like warning the planet."


 * Halsey: "Professor Sorvad's final entry in his field notes made reference to a "latchkey discovery". Latchkey... not a word he would use lightly. So let's hope that the data module your Lieutenant Commander stole contains it."


 * Carter-A259: "Kat?"


 * Halsey: "Before you ask, I was alerted the moment you attempted to access its contents. As I am with any unauthorized tap."

Kat walks over and places the module in a container in the shield door.


 * Halsey: "That data is classified Tier One... I could send you to the brig for interfering with my work."

Halsey pulls the container towards her side of the shield door and retrieves the module.


 * Carter-A259: "Maybe you'd like to join her."


 * Halsey: "...I'm sorry?"


 * Carter-A259: "We're currently under emergency planetary directive, Winter Contingency. I'm sure you're familiar with the punishment for civilian interference with a Spartan deployment."


 * Halsey: "Are you threatening me, Commander?"


 * Carter-A259: "Just making a reading suggestion, ma'am."

Carter and Kat start to leave, while Halsey begins to examine the module.


 * Carter-A259: "Let's move, Noble Team."

Noble Team departs, with the exception of Jorge, who lingers briefly.


 * Jorge-052: "Ma'am?"


 * Halsey: (examining the module) "That... will be all, Jorge."

Fade to black.

Level ends.

Trivia

 * The Reach Racer easter egg can be found on this level.
 * This level is home to a popular credit farming method. Simply sprint from the very beginning of the level to the closed gate where the target locator is found, past down the incline. Do not kill too many enemies. You will receive a checkpoint either before or after you pick up the locator, which you can then use upon the hordes of Covenant coming down the incline behind you. If you are lucky you may even receive a checkpoint right after arming the locator and thus speed up the kill count after each revert and subsequently, the credits you earn. This also boosts your Splash Damage and Walking Tank commendations, which also reward you with large amounts of credits. Contrary to popular belief, you cannot get banned for utilizing this method.
 * From leaked early development screenshots, the initial area the player starts in originally contained an anti-air gun. Also, at the end, a Spartan Laser could be used.
 * If the player holds onto the target locator until after the communications array and antiaircraft gun have been activated the target locator will replenish, allowing the player to call in up to two more bombardments. The locator will only replenish to two bombardments; if the player has only used the locator once they will only receive one more bombardment; if they have not used it at all they will not receive any more. This method can particularly useful for eliminating opposition outside Sword Base as well achieving large multikills on the ramp just inside the gate. The player should use the designator before entering the building, after which it will become effectively useless.
 * There will be a Phantom hovering above and around Airview Base for the AA gun to destroy when activated. If it is destroyed by the player, it will be immediately replaced by another Phantom, and so on until the anti-aircraft gun is activated. The Phantom(s) in question will not attack the player; they only shift position from one side of the area to the other to avoid hostile fire.  These two conditions on the Phantom(s) allow for very easy point (but not cR) farming (each Phantom is worth 1000 points but no credits).  It is recommended to drive a Warthog with a Marine carrying a Rocket Launcher as the Passenger (Kat will be on the LAAG and rather useless), which will keep pace and in range with the Phantom flying back and forth, or use a Wraith (steal one instead of blowing it up right after Rally Point Alpha) for higher damage per shot.
 * Once inside Sword Base, you can find several Grunt Heavies wielding Plasma Rifles for the first time in-game as starting weapons (you are able to switch weapons with Grunts in Halo 2 to give them Plasma Rifles, but they never spawn with them). This corroborates John-117's witnessing Unggoy with Plasma Rifles in other battles.
 * It is possible to find many BOBs on this level.
 * This is the only campaign level to include the Target Locator.
 * At the area where you destroy two Wraiths with the designator (directly outside the entrance to Sword Base), a second Target Locator spawns on the inner end of the bridge that leads to Airview Base after activating both the anti-air gun and the communications relay.
