Transcript

{Cutscene}

Fade in to an ONI facility. Dr. Catherine Halsey walks down a walkway in the middle of a dark circular room, lined by tall black monoliths. Reaching its end, Halsey places her left hand on a scanning panel and the door opens to let her into her lab. Inside, classical music is softly playing. As she passes her desk, Halsey sets her journal on it. The desk is adorned with books, ONI paper files, an active holoscreen, and a framed photo of Miranda Keyes. Nearby is a hologram of a human brain.

Halsey reaches into the wall and pulls out an armored matrix. She then heads to the far end at the lab, where there is a glowing blue holotank.

• Halsey: (voiceover) Spartan Locke.

Halsey plugs the armored matrix into the holotank. Standing on it is a projection of a blue woman, Cortana.

• Halsey: (voiceover) I have spent enough years with ONI to know the truth.

Halsey smiles at her AI and Cortana smiles back.

• Halsey: (voiceover) Once this is over, after all I have done...

Halsey turns the handle of the matrix in the tank. Cortana's hologram vanishes as she's transferred to its chip.

• Halsey: (voiceover) They'll order you...

The room darkens and Halsey's smile fades.

• Halsey: (voiceover) ...to kill us both.

{Cutscene}

Fade in to Jameson Locke's helmet, lying on a seat inside a Pelican's troop bay.

Cut to the Microsoft Studios logo.

A rotating cylindrical holotank lowers from the ceiling. It activates, displaying several holographic photos of destruction on several human colonies.

Cut to the 343 Industries logo.

Lasky briefs Fireteam Osiris.

Cut to the Pelican bay. Members of Fireteam Osiris are looking at the holotank. An additional screen appears on it as Thomas Lasky begins his transmission.

• Thomas Lasky (Video COM): "Fireteam Osiris. Over the last 72 hours, five colonies have experienced identical events. Massive destruction, Forerunner in origin."

Olympia Vale stands up. A 3D portrait of Catherine Halsey appears on the holotank.

• Lasky (Video COM): "Dr. Catherine Elizabeth Halsey has managed to contact us."

Edward Buck scratches his chin.

• Lasky (Video COM): "She claims to have information on these attacks."

Holly Tanaka passes an M6H magnum to Vale as they look at the holotank. Another screen appears on it as Sarah Palmer joins in.

• Sarah Palmer (Video COM): "Halsey is currently in Covenant custody on the surface of Kamchatka."

Locke stands up as the holotank shows battle plans for Kamchatka.

• Palmer (Video COM): "Your mission is to insert behind enemy lines, retrieve Halsey and bring her back to Infinity."

The hologram of the Kamchatan mountain ranges disappears, and a Sangheili hologram replaces it.

• Palmer (Video COM): "Be advised. Dr. Halsey is accompanied by Covenant supreme leader Jul 'Mdama. If you have the opportunity…"

• Locke: "Understood, Commander."

• Lasky (Video COM): "Good luck, Spartan Locke. Infinity out."

The holotank shuts down.

• Locke: "Tracking gear online?"

Vale activates her Artemis Tracking System.

• Olympia Vale: "Affirmative."

Tanaka grabs her helmet from the overhead compartment and approaches the center of the Pelican.

• Holly Tanaka: "Say, before we make this jump, anybody want to say a few words?"

Buck stands and picks up his M45 shotgun, cocking it and holstering it on his back.

• Edward Buck: "I figure if God can hear how scared I am, so can everyone else. Locke, you buying the first drink when we're done?"

• Locke: "You ask, you buy."

Buck chuckles. Locke turns to the others.

• Locke: "Fireteam Osiris, the light is green."

Locke turns around and opens the troop bay door. Vale and Tanaka put on their helmets and jump. Buck smiles and passes Locke his helmet before putting on his own helmet and jumping off the Pelican. Locke puts on his helmet, turns around, and jumps. He joins the others in the sky. Cut to black:

Fireteam Osiris descends into battle.

Open to the four Spartans in free fall. Covenant starships are massed beneath, engaged in battle. The Spartans zoom through the fleet, passing enormous blockade runners and aiming for the mountain range below.

• Locke (COM): "Comms check."

Tanaka crashes into a Banshee, which explodes near Buck. He narrowly dodges the explosion while Tanaka's energy shields flicker and recharge.

• Tanaka (COM): "Comms working fine, Locke."

• Locke (COM): "Copy that, Tanaka."

A damaged Forerunner vessel crashes into a mountain peak and shatters.

• Buck (COM): "Spartan Buck online and ready."

• Vale (COM): "Spartan Vale online!"

The Spartans pass the crashed ship, "flying" close along the mountain slope. Thrusters on their suits control their fall.

• Locke (COM): "Weapons free!"

The Spartans orient themselves feet first to land.

• Buck (COM): "Contact!"

The Spartans tuck and roll upon hitting the ground, propelling their freefall momentum forward. They rush down a mountain slope into a snowy valley filled with Covenant infantry and vehicles.

Buck and Vale fire into a Sangheili Zealot and Unggoy Storm with their shotgun and assault rifle, while Locke leaps ahead and ground pounds a Wraith and two more Zealots, overturning it and stunning the Elites. Buck and Vale finish them off while Locke lands and takes out a Grunt with a Needler.

Buck and Tanaka leap into the air and perform two ground pounds, blasting away more Covenant. Tanaka shoulder-bashes an Elite and Jackal, smashing them both through a boulder which shatters on impact.

Locke shoots away a Jackal while Tanaka fires her SMG, jumping onto and over a Wraith. Her teammates join her in picking off Covenant, some chasing them in floating vehicles. A Phantom floats ahead of them and fires at the Spartans with its chin mounted turret. Flying low to the ground, it scrapes a hill, and Vale uses its momentary confusion to leap onto its open bay doors and rush inside.

Vale knocks two Jackals aside and charges at a Zealot and a Warrior. Both swing their energy swords at her, but she jumps onto the Zealot's arm and forces its blow into the Warrior, damaging its shields and briefly stunning it. The Zealot is then pushed into the Warrior as Vale turns to face the Jackals. Vale punches one Jackal in the face and shoots another with her pistol. She kneels to make the charging Zealot trip over her, then stands up to fire her pistol repeatedly into the Warrior's chest. She then kicks it and a Jackal out the Phantom, the latter screaming as it falls.

The two hit the ground, Buck running over them as he takes out a Grunt and a Sangheili with two shotguns blasts. Locke keeps pace to his right, and they leap off a cliff into the Covenant below. Buck ground pounds a lance of infantry, and Tanaka grabs a Grunt by the face while firing her assault rifle at a Jackal. A Grunt with a needler lunges at her, but Tanaka catches it, throws it behind her, and shoots it away.

Promethean constructs can be seen fighting the Covenant now. Ghosts rush past firing at Soldiers and Knights, while Phaetons battle the Phantoms overhead. Locke leaps over a pair of Ghosts and pulls the driver out of one of them.

A Phantom, the one carrying Vale, flies low and crashes into a Phaeton, wrecking both vehicles and killing the remaining Zealot onboard. Vale jumps out and uses her SMG to finish off a Soldier. It disintegrates into orange and grey ash.

• Vale (COM): "Heads up!"

The four turn to face behind them, seeing one of the Covenant blockade runners crashing at the peak of the valley they're in. It hits the ground and begins sliding toward them, bringing an avalanche with it.

The Spartans turn and run from the incoming starship, Vale picking off a Jackal and Buck finishing off a Soldier and Zealot. They run down the increasingly steep slope as fast as they can, but the crashing ship is coming closer.

As they approach a sheer cliff, Locke lands and rejoins them. Fireteam Osiris assembles and leaps off the cliff with the burning wreck behind them.

Cut to Locke's point-of-view, as he and Osiris slide down the cliff, which leads to a small canyon with Covenant below. Buck lunges at a Sangheili Storm, knocking it over and flinging its energy sword to Locke's hand. Another Storm roars and attacks Locke, but the Spartans stabs the sword in its throat. Vale kills a third Elite to his left, but there are still plenty of Covenant ahead of them.

• Tanaka (COM): "Incoming!"

Locke looks up to see a fragment of the blockade runner falling and crashing into the ground, its impact killing almost all the Covenant there. Only a single weakened Commander is left.

{Gameplay}

• Buck (COM): "We could've taken 'em."

• Locke: "Let's move. Vale, keep an ear on comms."

• Vale (COM): "Affirmative."

• Locke: "Buck, Tanaka, pull security."

• Tanaka (COM): "On it."

• Buck (COM): "Aye."

• Locke: "Halsey and 'Mdama are holed up inside a Forerunner structure ahead. That's our target."

• Vale (COM): "So Halsey called us."

• Locke: "She said there was something big out there, and gave Captain Lasky coordinates to find her."

• Vale (COM): "There must be something big."

• Buck (COM): "Or one hell of a trap."

---

• Sangheili: "They must not break through the line to 'Mdama! 'Mdama's work must continue or Sanghelios is lost to us!"

---

• Vale (COM): "All clear."

• Locke: "Move on toward Halsey's position."

• Locke: "Forerunner Soldiers! Up the cliffs! Get out!"

---

• Locke: "Soldier just teleported through that ice wall."

---

• Locke: "Promethean! All sides."

• Buck (COM): "We could push right up the middle, but that'd be rough. Might want to consider flanking them."

• Locke: "Move smart. Fire with a purpose."

---

• Buck (COM): "Area's clear. Move on."

• Locke: "Good work everyone."

• Vale (COM): "I noticed in the briefing Dr. Halsey lost her left arm. When did that happen?"

• Locke: "Jul did it. No idea when or why."

• Tanaka (COM): "Reckon it wasn't an argument, or he'd have cut off her head instead of her arm."

• Locke: "Systems analyzed. Looks like there's an override switch near the top of the room."

• Buck (COM): "The door's sealed tight."

• Tanaka (COM): "Forerunner security station. Must be in lockdown."

• Buck (COM): "Any way to lift it?"

• Locke: "The Artemis can analyze Forerunner systems. Might be a way to override this door."

• Tanaka (COM): "This Artemis thing one of your old ONI toys?"

• Locke: "Similar. I convinced Commander Palmer to outfit us with prototypes."

• Locke: "Let's see... this should do it."

---

• Locke: "The door's open."

• Tanaka (COM): "The Artemis did the trick."

• Vale (COM): "Locke, listen to this."

• Jul 'Mdama: (speaking Sangheili)

• Vale (COM): (translating) "They're assaulting the back of the temple. Bring in the Kraken."

• Locke: "Kraken sighted!"

• Jul 'Mdama: (speaking Sangheili)

• Vale (COM): ""Hold position. Buy more time." Jul's getting desperate."

• Tanaka (COM): "How'd you learn to speak Sangheili, Vale?"

• Vale (COM): "When I was a kid, I was stuck on a diplomatic shuttle adrift in deep space for six months. My options were be real bored or spend the time getting smart."

---

• Locke: "Our destination is on the other side of this battlefield! Watch out for the Kraken! The Covenant are trying to use it to break the Promethean lines!"

• Buck (COM): "I'd rather not get stuck between them!"

---

• Sangheili: "Hold your ground! We must not break!"

---

• Vale (COM): "Kraken is falling back! Forerunner defenses were too much for it!"

---

• Locke: "Keep moving toward Halsey's position."

---

• Tanaka (COM): "Must've dealt a blow to 'Mdama's authority when the Prometheans turned on him. Gained a lot of followers styling himself as a Forerunner prophet."

• Locke: "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."

• Buck (COM): "Well it could stand to break a little faster if you ask me."

• Locke: "We're close to Halsey's position."

• Halsey: (recording) "Obtained scans of new Forerunner glyphs. One is completely new. Running the other through the system reveals it contains a similar design to an ancient Sangheili symbol. This symbol referred to as "demon who sleeps in the ground and must not wake". How that relates to this symbol I am unsure."

• Locke: "Knights!"

• Tanaka: "New kind too. Like they reported on Oban."

• Locke: "Concentrate fire on the broken armor."

• Locke: "Don't let them through to Halsey. We need her alive."

• Buck (COM): "Alright, danger is clear."

• Locke: "We move on Halsey and Jul."

{Cutscene}

Osiris assembles at the exit door as it opens to reveal the entrance to Jul's balcony. The four Spartans head down the hallway, weapons at ready.

Cut to bird's-eye-view of the temple balcony. Zealots stand guard and a Phantom holds position nearby it. Jul paces in the center while Halsey reads her data pad.

• Jul 'Mdama: (angrily) "What is the problem?"

• Halsey: "Hmm, there are several. Would you like to discuss the finer points of casual reconciliation?"

• Jul 'Mdama: "More human sarcasm."

• Halsey: (smiles) "So you have learned something from me."

• Jul 'Mdama: "You claimed to be able to access—"

• Halsey: "And I can. However, I did not claim to be able to access it instantaneously."

Cut to Osiris heading down the hallway. Tanaka raises her assault rifle to guard the rear while the others reach cover to prep for attack.

• Jul 'Mdama: "The security situation is not clear. There is no time to dither."

Cut to Locke's POV, as he watches Jul circling Halsey and the guards around them.

• Jul 'Mdama: "You will also accord me the respect befitting of the Didact's Hand."

• Halsey: "Mmmm, seems your fingers are in open rebellion, Hand."

• Jul 'Mdama: "Enough!"

Buck sneaks forward and raises his scoped-on Lightrifle. He aims it at a Zealot's head.

• Buck: (low) "Hey good lookin'."

• Jul 'Mdama: "Resume your work."

Vale hides behind a barrier and watches a guard to her left.

• Vale: "Eyes on target."

Halsey sighs frustratedly and starts backing away.

• Halsey: "This location does not serve my needs. When she makes another transmission, I must triangulate—"

• Jul 'Mdama: "I tire of this, doctor! You have been chasing shadows for weeks to no avail."

Locke, kneeling, turns his head to Buck and nods. Buck aims his lightrifle, and the targeted Zealot falls. Tanaka turns forward and fires her assault rifle, while Locke dashes to the balcony center, punching away guards and heading straight for 'Mdama.

Vale jumps up to a Zealot guard and leaps off of his head. She lands behind it and the Elite chases her while she shoots it with her pistol. When he gets close, Vale flings him off the balcony and the Elite falls to his death.

'Mdama pushes Halsey away and draws his energy sword.

• Jul 'Mdama: "Kill them!"

Locke, watching Tanaka fight the guards, turn to face 'Mdama. Halsey looks back at Locke worriedly.

Locke charges at 'Mdama, then ducks and slides when the Sangheili swings his sword, his thrusters propelling him quickly past it. He gets up and stabs 'Mdama in the chest, stunning the Elite. Locke swings around and jumps on 'Mdama's back. 'Mdama tries to shake him off, but Locke stabs him in the neck, 'Mdama groaning in pain.

Cut to Buck punching an Elite in the face and Vale jumping high and shooting down more. Tanaka surveys the site with her rifle.

• Tanaka: "Clear."

Spartan Locke standing over the body of Jul 'Mdama.

Locke gets off 'Mdama and pulls out his knife as the Covenant leader falls dead. Locke steps away and turns to face Halsey.

• Locke: "Dr. Halsey. Captain Lasky would like a word with you."

• Halsey: "It took you long enough."

Level ends.

Production notes

• The second cutscene was originally released online as the Halo 5: Guardians Opening Cinematic trailer. Small changes have been made to the final version, such as Vale visibly shooting a Sangheili Warrior as opposed to her fight being obscured by the frame.
• In the final cutscene, Dr. Halsey erroneously refers to causal reconciliation as casual reconciliation.
