'''The Ark''' is the seventh [[campaign]] level of ''[[Halo 3]]''.
It takes place in a desert that comprises one of the center-most regions of the Ark, located 2<sup>18</sup> light-years outside the [[Milky Way]] galaxy's center. In this level, the [[Fleet of Retribution|Sangheili]] and the [[human]]s side with [[343 Guilty Spark]] and his [[Sentinel]] allies to access the [[Cartographer#Installation 00|Cartographer]] and find The [[Prophet of Truth]]. Beating this level on [[Normal]] unlocks the [[EVA-class Mjolnir]] shoulder pads. Beating this mission on [[Heroic]] unlocks the shoulder pauldrons to the Elite [[Flight Harness]] [[Armor customization (Halo 3)|armor permutation]]. Beating this level on [[Legendary]] gets you the [[EOD-class Mjolnir]] shoulder pads. Getting more than 50,000 Meta Game points will unlock the [[Ranger (achievement)|Ranger]] achievement, worth 10 [[Gamerscore]].

==Summary==
The joint UNSC-Sangheili fleet crosses [[Excession|the Portal]] and arrives in orbit over a massive Forerunner structure.  While Commander Miranda Keyes and Shipmaster Rtas 'Vadum engage Truth's [[Truth's fleet|much larger fleet]], John-117 and a contingent of Marines and ODSTs are deployed to the surface of the Forerunner structure.  Upon landing, John-117 and a team of ODSTs head out on foot and clear out two large Covenant-held positions and stop the Jiralhanae from setting up an [[Skar'wa-pattern Mantis|anti-aircraft battery]]. Keyes orders the Master Chief to clear a landing zone for the {{UNSCShip|Forward Unto Dawn}}.

The Chief and the ODSTs meet up with a group of Marines whose Pelican was shot down.  The Marines inform the Chief that there's a good landing zone for the ''Forward Unto Dawn'' nearby.  After retaking the Pelican crash site, John-117 and his allies commandeer an assortment of vehicles and drive off to secure the LZ. Along the way, the Chief discovers a large Forerunner wall built between the cliffs. The entrance to the wall is guarded by [[Sentinels]] which attack the Covenant but leave the humans alone. Johnson arrives in a Pelican and informs Commander Keyes that Hocus has found a structure located on the other side of the wall. Keyes deduces it's a Cartographer which they can use to locate the Prophet of Truth.  

The Chief arrives at the ''Forward Unto Dawn's'' intended landing zone and defeats the Covenant forces occupying it including a pair of Anti-Air Wraiths.  With the landing zone secure, the ''Forward Unto Dawn'' enters the installation's atmosphere and deploys reinforcements, including Scorpion tanks. Keyes orders the Master Chief to take the convoy through the wall and locate the Cartographer. John-117 takes a tank and leads the armored convoy against a large force of Covenant vehicles and infantry. [[343 Guilty Spark]] accompanies the humans and opens the entrance to the wall, allowing John-117 to enter on foot. Inside, he activates a light bridge, allowing the UNSC convoy to pass through the wall.

Upon reaching the other side, the UNSC encounters another large force of Covenant vehicles, including a Scarab, guarding the structure containing the Cartographer. After a prolonged battle, the Chief and his allies prevail.  At the same time, Shipmaster 'Vadum reports that Truth's fleet has been defeated. The Chief heads up to the top of the structure, where he teams up with Thel 'Vadam and a pair of Marines. 343 Guilty Spark opens the doors, allowing the Chief and his allies to enter.  The group fights their way into the lower depths of the building and finally locate the Cartographer. Upon accessing the Cartographer, John-117 discovers that they are outside the Milky Way galaxy, and that this installation is, in fact, [[Installation 00|the real Ark]].  Guilty Spark locates the Prophet of Truth, who has activated a protective barrier around himself. Spark then discovers [[Installation 08|something else]], but before he can reveal what it is, a hostile Phantom arrives. Johnson contacts the Chief and warns him that additional Covenant forces are heading their way. Thel 'Vadam hijacks a Banshee and engages the Phantom, while the Chief and the Marines head to the lower level to meet up with their evac. After defeating more Covenant troops, including a Jiralhanae Chieftain, the Chief is picked up by Johnson's Pelican. As they leave, a massive force of Sentinels are seen departing on an unknown priority mission. Though Guilty Spark wants to focus on finding Cortana's solution to the Flood, Commander Keyes states that they must stop the Prophet of Truth first.

[[File:H3 - Shadow of Intent Bridge.png|thumb|300px|The Major and 'Vadum on the ''[[Shadow of Intent]]'s'' bridge.]]
''The [[Sangheili]] {{Pattern|Ket|battlecruiser}}s and {{Class|CAS|assault carrier}} arrive at the other side of the [[slipspace portal]]. A colossal structure is below them, and [[Truth's fleet|a Covenant fleet]] straight ahead.''

''Cut to the bridge of the ''[[Shadow of Intent]]''.''

*'''[[Sangheili Major]]''': "Brute ships. Staggered line! Shipmaster, they outnumber us, three-to-one!"

*'''[[Shipmaster]] [[Rtas 'Vadum]]''': "Then it is an even fight. ''(COM)'' All cruisers, fire at will! ''Burn'' their mongrel hides!"

''[[ODST]]s and [[Marines]] board a [[D77H-TCI Pelican|Pelican]] with [[John-117]]. Cuts to the cockpit of the same Pelican.''

*'''[[Commander]] [[Miranda Keyes]] (COM)''': "[[Anodyne Spirit|Truth's ship]] isn't taking part in the attack. He must've gone to ground!"

*'''[[Sergeant Major]] [[Avery Junior Johnson]]''': "Roger that, Ma'am! We're on him! (''to [[Hocus]]'') Kick the door."

''Hocus nods, and presses a button on the controls. The Pelican drops out of the {{UNSCShip|Forward Unto Dawn}} along with six other Pelicans. The massive underside of the ''Shadow of Intent'' can be seen flying on top of the ''Forward Unto Dawn'', which is seen leaving the ''Shadow of Intent's'' underside. As the dropships breach through the Covenant fleet, one of the Pelicans takes a hit from a [[Kai-pattern Seraph]] fighter-interceptor.  Its starboard engine bursts into flame and it spirals out of control and explodes. The other Pelicans make it through unscathed. As they enter the atmosphere, the Chief checks on Johnson and Hocus in the cockpit, then returns to the back, where several Marines and ODSTs sit, readying themselves for battle.''

*'''Johnson (COM)''': "We good, Hocus?"

*'''Hocus (COM)''': "She's a little cooked, Sergeant Major... But she'll hold."

''The Master Chief picks up a [[SRS99D|sniper rifle]] holstered in the troop bay.''

*'''Johnson (COM)''': "Alright. Pop the hatch!"

''The Master Chief slams a magazine into his rifle. The troop bay hatch opens, revealing a massive desert (In Co-op, [[Thel 'Vadam|the Arbiter]], with a [[Type-50 particle beam rifle]], stands up from the right side of the troop bay and moves to sit on the left side). The Chief walks to the right side and sits down.''

'''{''Gameplay''}'''

*'''ODST #1''': "That's some view."

*'''Johnson (COM)''': "Enjoy it while you can, Marines. Soon as we land, we're right back to it. Priority one: secure a landing zone for the Commander's Frigate. Keep your eyes and ears open. We need all the intel we can get... on wherever the hell we are."

''The Pelicans touch down on a cliff side.''

*'''Johnson (COM)''': "Stand to, Marines!"

*'''Marines''': "Oo-rah!"

*'''Johnson (COM)''': "Go, go, go!!"

===Installation 00===
'''''Sharpshooter.'''''

[[File:H3 ArkStrikeTeam.png|thumb|300px|John-117 and two ODSTs deployed from the Pelican.]]
''The Master Chief (and the Arbiter, in co-op) and two ODSTs jump out of the Pelican. The Marines remain on-board. Another Pelican lands, dropping off two more troopers (In 3-4 player Co-op, [[N'tho 'Sraom]] and [[Usze 'Taham]] will come from the second Pelican). As the team moves on, one spots what looks like a galaxy in the sky.''

*'''ODST #2''': "Hey, check it out. In the sky. Is that-?"

*'''ODST #1''': "Hey, focus! We got a job to do."

''The Marines take up positions on a ledge, overlooking a Covenant encampment.''

''An ODST with red armor trim (Squad Leader) turns to the Chief.''

*'''ODST leader''': "Chief, eyes on."

''The ODST leads the team up the hill.''

*'''ODST leader''': "Got a good angle."

''The team sets up firing positions.''

*'''ODST leader''': "You take the first shot."

*'''[[Prophet of Truth]] (Hologram)''': "My Dreadnought cannot rise. Even now it is engaged, turns deftly in the wards of this new world. Do not relent until the [[Fleet of Retribution|heretic]] ships are smashed!"

''The Chief fires, and the rest of the team opens fire. Through tactical advantage and sniper fire, the enemy soldiers are wiped out. The team continues on.''

*'''ODST #1''': "We got more enemy contacts ahead, move out!"

[[File:H3 ArkAmbush.png|thumb|300px|The UNSC team comes across a Mantis being assembled.]]
''The team goes through a cave. A [[Ru'swum-pattern Phantom|Phantom]] is assembling an [[Skar'wa-pattern Mantis|anti-aircraft battery]] on the other end.''

*'''ODST leader''': "They're setting up an AA battery. That thing'll tear the ''Dawn'' apart... We'll wait for you to take the shot."

''The team engages the enemy. The Phantom abandons a piece of the battery and flees. Having the lower ground, the Covenant soldiers start to retreat. Another Phantom drops off a [[Mgalekgolo]] pair. The Master Chief finally takes them down, and the team continues up the hill, engaging a large group of [[Unggoy]] and a [[Jiralhanae]] [[Jiralhanae Captain|Captain]].''

*'''Keyes (COM)''': "Chief, I'm giving the Brutes all I've got...but this is a heavy-weight fight! The ''Dawn's'' only got the tonnage to last a few rounds. Find me a place to set her down. Over!"

''If the player stalls:''

*'''ODST #1''': "The area is secure, let's move ahead."

''or''

*'''ODST #2''': "Chief, Commander Keyes is counting on us to clear the LZ."

''If the player continues to stall:''

*'''Johnson (COM)''': "Come on Chief, move ahead. Go, go, go!"

''The Master Chief and the team head through the structure at the top of the hill. Coming out on the other side of the structure, they see a squad of dead [[Unggoy]]. A burning [[GA-TL1 Longsword|Longsword]] roars through the canyon ahead.''

*'''Longsword Pilot (COM)''': "Thrusters are gone, I can't control it!"

''A muffled crash is heard a few seconds later.''

''A pair of Marines reveal themselves.''

*'''[[Private First Class]] [[Chips Dubbo]]''': ''(whispering)'' "Flak got our Pelican too, sir. But before we went down, we spotted a good LZ. If we can get to our vehicles, we'll lead you to it."

''The Chief and the others look at an area at the bottom of the ledge they are standing on. Several [[Unggoy]] and [[Jiralhanae]] are guarding a crashed Pelican and [[M274 Mongoose|Mongooses]] which presumably fell out when the Pelican was shot down. The Chief and his allies engage the Covenant patrol and annihilate them.''

''If Chief stays by the downed Pelican he can pick up radio transmissions of the ongoing space battles above the installation. These play in a random order, though some phrases are played in quick succession as responses to others. There are several Longsword pilots. All pilots have been marked as "unknown" here.''

*'''Rtas 'Vadum (COM)''': "Hit them again! And again! And again!"

*'''Unknown Longsword Pilot (COM)''': "Got a lock! Fox, Fox!"

*'''Keyes (COM)''': "Negative, protect the Pelicans!"

*'''Rtas 'Vadum (COM)''': "Now, close for the finish!"

*'''Unknown Longsword Pilot (COM)''': "Negative, get out of there!"

*'''Rtas 'Vadum (COM)''': "Let your [[MAC Gun|cannons]] roar."

*'''Rtas 'Vadum (COM)''': "Broadside! What fools to face our guns!"

*'''Keyes (COM)''': "Fire pods one through twelve. [[Archer]]s away."

*'''Keyes (COM)''': "New contacts at point two-three-eight!"

*'''Unknown Longsword Pilot (COM)''': "Affirmative. I see it...."

*'''Rtas 'Vadum (COM)''': "No! I will handle those myself."

*'''Unknown Longsword Pilot (COM)''': "Seraphs, on my six!"

*'''Rtas 'Vadum (COM)''': "Stay away from those cruisers!"

*'''Keyes (COM)''': "Understood. Engage those Seraphs!"

*'''Unknown Longsword Pilot (COM)''': "Splash one, coming about."

*'''Keyes (COM)''': "Let the Elites handle those cruisers."

*'''Rtas 'Vadum (COM)''': "Full shields! Ramming speed!"

*'''Unknown Longsword Pilot (COM)''': "Point laser fire, break off!"

*'''Unknown Longsword Pilot (COM)''': "I'm hit, I'm hit!"

*'''Keyes (COM)''': "Watch your fire, watch your fire!"

*'''Unknown Longsword Pilot (COM)''': "I've lost avionics - going to try and hit their carrier! Goodbye, guys."

*'''Unknown Longsword Pilot (COM)''': "All squadrons, form up! Form up!"

*'''Rtas 'Vadum (COM)''': "A mark of honor for that kill."

*'''Rtas 'Vadum (COM)''': "Suppress with main point laser batteries."

*'''Rtas 'Vadum (COM)''': "Forward lances, draw their fire."

*'''Rtas 'Vadum (COM)''': "...burn."

*'''Keyes (COM)''': "Affirmative, that's a hit."

*'''Rtas 'Vadum (COM)''': "They have been gutted stem to stern."

*'''Rtas 'Vadum (COM)''': "Look at it blister and burn."

*'''Keyes (COM)''': "Charge the MAC. Give me a firing solution."

*'''Keyes (COM)''': "Stand by to jettison the [unintelligible: "HEVs"?] on my mark."

''Two [[Qavardu Workshop Prowler|Brute Prowlers]] show up. One parks near the Mongooses and its Jiralhanae occupants all leap out while the other circles the area, firing at the UNSC forces. Once the Jiralhanae are all killed, the Marines mount up on the Prowlers and working Mongooses.''

*'''Dubbo''': "Mount up. Let's find that LZ. Follow us, sir, all the way down this canyon."

''The team mounts up and moves on through the canyon, clearing [[Covenant]] patrols and passing the Longsword's wreckage. There's a working [[M12 LRV|Warthog]] nearby that the Chief can use.''

''The team continues on, wiping out a small group of Covenant camped around a crashed Phantom. Transmissions from Jiralhanae warships can be heard from the Phantom.''

*'''Jiralhanae Commander (COM)''': "Nooooo! Hit the carrier! Kill the [[Rtas 'Vadum|Half Jaw]] and his crew!"

*'''Jiralhanae Commander (COM)''': "Keep these fools at bay. Drive the heretic ships back through the Portal!"

*'''Jiralhanae Commander (COM)''': "Their cruisers mixed with ours! Watch your fire!"

*'''Jiralhanae Commander (COM)''': "Do not fear the [[San'Shyuum|Prophets']] wrath, because if you fail I will have your hide!"

[[File:H3 Ark SentinelsVsCovenant.png|thumb|300px|The Covenant attacking Aggressor Sentinels at the wall's upper floor.]]
''The assault team heads into another canyon with a large [[Forerunner]] wall built in between the cliffs. Fighting their way through a large enemy force, the team makes it to the higher level, where Covenant troops are engaged with [[Aggressor Sentinel]]s.''

*'''ODST #2''': "Careful, sir! Brutes must've tripped a defense system."

''The UNSC forces and the Sentinels clear the top floor. The Sentinels don't open fire on the humans. Johnson's Pelican flies over the wall and hovers.''

*'''Johnson (COM)''': "Ma'am, Hocus almost got her wing shot off. But we spotted a structure on the other side of this wall. It matches [[Cortana]]'s description of the [[Cartographer#Installation 04|map room]] on the [[Installation 04|first Halo ring]]."

*'''Keyes (COM)''': "[[Cartographer#Installation 00|A Cartographer]]. Good. Should help us fix Truth's location. Secure the LZ, then we'll push through that wall."

*'''Johnson (COM)''': "Roger that. Follow my Pelican, Chief! The LZ's this way."

''The Sentinels follow Hocus' Pelican. The Marines are nervous about their presence.''

*'''ODST #1''': "Tidy little bastards. Hope they never decide to clean us up."

*'''Marine #1''': "It's like they don't even ''see'' us."

*'''ODST #1''': "Oh, they see us all right. They just haven't decided what to do with us yet."

''The team and the Sentinels continue along the other canyon, towards the LZ. Wiping out a pair of [[Karo'etba-pattern Ghost|Ghosts]] under a large Forerunner structure, the force presses on. Near a cave, they find two Marines pinned down by a large assault group of Covenant, including another pair of Ghosts (on higher difficulties, a Jiralhanae wielding a [[Pez'tk-pattern fuel rod gun|fuel rod gun]] is also present). The Sentinels and the Marines clear the area. The UNSC forces meet up with the two Marines.''

*'''ODST #1''': "The LZ's through this cave, sir. Watch yourself; got Covenant heavy armor!"

''The team heads through the cave. A large Covenant force is encamped in the next area, including a [[Zurdo-pattern Wraith|Wraith]], a brace of Ghosts, Jiralhanae and Unggoy-operated turrets. After a struggle, the team eventually prevails. Out on a sandy plateau, two [[Ogab'd-pattern anti-aircraft Wraith|Anti-Air Wraiths]] are filling the sky with fuel rod fire. The team takes out the Anti-Air Wraiths and any remaining Covenant.''

*'''Johnson (COM)''': "That did it. LZ's clear."

''or''

*'''Marine #1''': "Oo-rah! The LZ's clear!"

''or''

*'''ODST #1''': "OK. Tell us what you need."

*'''Johnson (COM)''': "Commander? Bring her down."

*'''Keyes (COM)''': "Roger that. Beginning my descent."

*'''ODST #2 or Dubbo''': "Look! Up high! Here she comes!"

*'''ODST #1''': "Is the ''Dawn'' rated for atmosphere?"

*'''ODST #2 or Dubbo''': "Guess we're gonna find out...hey! ''Take cover''!"

''The {{UNSCShip|Forward Unto Dawn}} swoops in dramatically, kicking up dust and sending the vehicles and debris from the previous battle tumbling and flying across the plateau.''

===Forward Unto Dawn===
'''''Armor up.'''''

[[File:H3  Ark ForwardUntoDawn.jpg|thumb|300px|The ''Forward Unto Dawn'' arrives at the landing zone.]]

*'''Keyes (COM)''': "Thanks, Chief. I wouldn't have lasted much longer up there. Come to the back of the frigate."

''If the player is away from the back:''

*'''Johnson (COM)''': "C'mon, Chief! Let's see what the Commander has in her arsenal..."

''The ''Forward Unto Dawn's'' hangar lowers, revealing three [[M808 Main Battle Tank|Scorpion]] tanks and a [[M12 Warthog|Warthog]]. [[343 Guilty Spark]] descends as well.''

*'''Keyes (COM)''': "Did the Elites get a fix on the Cartographer?"

*'''Johnson (COM)''': "Yes, ma'am; just on the other side of that wall. But it's surrounded by Brute heavy armor."

----
''If the player skipped the wall section leading to the Cartographer:''

*'''Keyes (COM)''': "Johnson, have the Elites found anything?"

*'''Johnson (COM)''': "A structure on the other side of that wall, ma'am. But it's surrounded by Brute heavy armor."
----

*'''Keyes (COM)''': "Don't worry; I've got a plan. If we can't fly over the wall, we'll go right through it. Chief, take one of the tanks, lead the way. If you find any locked doors, Spark will be happy to pry them open."

*'''343 Guilty Spark (COM)''': "I will certainly try my best, though I am unfamiliar with this facility."

*'''Johnson (COM)''': "Alright then, you heard the lady."

[[File:H3 Stacker Marines Arrival.jpg|thumb|300px|Stacker and his Marines are deployed from Johnson's Pelican.]]
''The tanks and Warthog leave the hangar bay, and Johnson's Pelican drops off [[Marcus Stacker|Gunnery Sergeant Stacker]] and a few of his Marines to commandeer the vehicles.  Any surviving ODSTs from the first part of the level will board the Pelican.''

''The Monitor hovers near one of the Scorpions.''

*'''343 Guilty Spark''': "Shall I help you choose a vehicle, [[Reclaimer]]? This one seems in very good condition, primitive armor not withstanding."

*'''Johnson (COM)''': "A tank's a tank, light-bulb. Pick one, Chief. Get back to the wall. I'll help the Commander secure the ''Dawn''. Then we'll meet you at the Cartographer."

''The player chooses a vehicle while the rest of the Marines mount up.''

*'''Johnson (COM)''': "Mount up - let's roll!"

*'''Marines''': "Oo-rah!"

''The convoy starts to move out.''

''[[Karo'etba-pattern Ghost|Ghosts]] and a [[Qavardu Workshop Prowler|Prowler]] pour out of the cave in the cliff. The Scorpions immediately open fire.''

''After the convoy scores a kill:''

*'''[[Gunnery Sergeant]] [[Stacker]] (COM)''': "Hey, how does 90 millimeters of tungsten strike you?"

''The convoy destroys all hostile vehicles.''

*'''Marine #2 (COM)''': "Tank beats Ghost!"

''A [[Mgalekgolo]] pair charge out of the cave. The UNSC forces destroy them with little effort.'' 

*'''Marine #2 (COM)''': "Tank beats Hunter!"

''On the other side of the cave, a [[Ru'swum-pattern Phantom|Phantom]] is setting up a [[Covenant watchtower]]. If the Chief shoots it down and destroys the tower:''

*'''Marine #2 (COM)''': "Tank beats ''everything''! Oh, ''man!'' I could do this all day!"

[[File:Ark Level Scorpion.jpg|thumb|300px|John-117's Scorpion fighting through Covenant vehicles.]]
''The convoy makes its way back to the wall where a locked door prevents any entry into the [[Forerunner]] facility. Armor resistance in the form of Wraiths, [[Barukaza Workshop Chopper|Choppers]], and Ghosts along with various Covenant infantry defend it.''

*'''Stacker (COM)''': "All armor, form up on the lower doorway. Chief, get upstairs; have your robot pick that lock!"

*'''343 Guilty Spark (COM)''': ''(indignant)'' "I beg your pardon? I am 343 Guilty Spark, [[Monitor]] of [[Installation 04]]."

*'''Stacker (COM)''': "Yeah, well...you're also our ticket through this wall. So if you don't mind?"

*'''343 Guilty Spark (COM)''': "I will gladly aid the Reclaimer's progress."

''The Chief and the Marines attack the facility's upper level.''

*'''343 Guilty Spark (COM)''': "Reclaimer, come to the upper doorway, the others can take the lower one."

''If the player waits:''

*'''Stacker (COM)''': "We'll go along, Chief, you check the upper floor. Make sure we have a path through the wall!"

''If the player still doesn't follow 343 Guilty Spark:''

*'''Johnson (COM)''': "Armor's gotta go along, Chief, you take the upper floor, make sure they have a path through the wall!"

''While the Master Chief storms the upper level, the other two tanks and other vehicles meet up at the lower door, clearing any resistance along the way. The Chief secures the top floor. 343 Guilty Spark arrives on the scene.''

*'''343 Guilty Spark''': "Please, use caution; avoid collateral damage! While this facility looks quite hardy on the surface, there are undoubtedly delicate structures below the façade. ''(pause)'' Odd, for a doorway to require such robust security protocols. One moment, Reclaimer."

''The Monitor opens the door.''

*'''343 Guilty Spark''': "There we are. Please, follow me."

''If the player goes back to the bottom of the wall:''

*'''Johnson (COM)''': "Chief! Get back up there and make sure we have a clear path through the wall."

''The Chief hops out of the Scorpion and follows Guilty Spark into the Security Wall. The Marines take the Scorpion down to the lower doorway.''

''Inside the structure, the Chief encounters a Sentinel. It stares at him as he passes by. The Monitor opens another door; the escorting Sentinel follows. Spark leads the Chief to a platform overlooking a deep chasm. The UNSC forces have gathered below on the left side of the chasm, and are waiting to cross.''

''Spark shows the Chief a control panel at the edge of the platform.''

*'''343 Guilty Spark''': "Here, this panel will activate a bridge."

''If the player stalls:''

*'''343 Guilty Spark''': "Allow your companions to cross below."

''If the player still waits:''

*'''343 Guilty Spark''': "Place your hand on the pad, Reclaimer."

''The Master Chief activates the panel. The bridge immediately lights up. The tanks and Warthogs move across; Guilty Spark opens another door. The Terminal behind the Chief is now accessible.''

*'''343 Guilty Spark''': "Excellent. This way!"

''Guilty Spark looks at the Sentinels, studying their differences in behavior and the odd high security levels.''

*'''343 Guilty Spark''': ''(hums)'' "Sudden clarity! These Sentinels were trying to deny access to the lower levels of this facility. A wise decision, given [[Covenant|the Meddlers]]' preference for...destructive acquisition."

*'''Keyes (COM)''': "Good work, Chief. Link up with our armor on the far side of the wall. Make your way down to the Cartographer."

''As the Chief continues on, the building shakes violently. Guilty Spark opens a door leading outside.''

*'''343 Guilty Spark''': "Hurry! To the Cartographer!" 

''As the Chief walks out, a massive leg slams down as a [[Deutoros-pattern Scarab|Scarab]] walks right over him.''

*'''Johnson (COM)''': "Heads up, Marines! We got trouble."

''A Warthog with an [[M68 Gauss Cannon]] appears from the rocky area. Pursuing Ghosts kill the Gunner. The Warthog driver finds the Chief and pulls over. In the distance, two other Warthogs have already engaged the
