Tip of the Spear
The level opens with Auntie Dot briefing Noble Team on the situation: A large Covenant invasion force has been discovered in the Viery Territory, and a joint UNSC military force has been mobilized to counter them across the continent. Noble Team's mission is to destroy Spire One, one of many large towers the Covenant have placed around their landing zone. Noble Six and Kat-B320 lead the charge at the Covenant positions, and destroy two Covenant anti-air guns. Noble Six, manning a Falcon's gunner seat, then joins Jorge-052 as they make their way to the Spire. As their Falcon passes through the Spire's energy shield, the craft is disabled by an EMP which sends it crashing to the ground, killing the crew and forcing the Spartans to continue on foot. Jorge and Six eventually make their way to the Spire, where the installation is revealed to be a teleportation terminal, used by the Covenant to transport troops to the ground from a yet-unknown source. After deactivating Spire One's energy shield, Six leaves the area on a Falcon accompanied by Carter-A259 and Jorge-052 as the UNSC Grafton destroys the Spire. Immediately after the tower collapses, the Grafton is destroyed by the previously cloaked Covenant supercarrier Long Night of Solace.
August 12, 2552 08:00 Hours
The Warthogs, led by Kat and Noble Six, charge towards the Covenant landing zone, followed by a group of Falcons. Carter is revealed to be on board a Falcon overlooking the Warthog driven by Kat. Noble Six rides shotgun in Kat's Warthog.
At this point, the subtitles show Jun saying, "Time to bake that cake we made last night!" The dialogue was confirmed by Bungie to have been a last-minute change.
Kat detonates the charge that was planted on the pylon in the previous mission by Jun, which is seen far to the right of the advancing Warthog strike force. The pylon is destroyed.
Banshees swoop down on the convoy and open fire, while Wraiths lob mortar rounds from a distance. The gunners on the Warthogs retaliate, firing at the Banshees. Type-26 Wraith mortar rounds tear into the convoy and destroy several of the advancing vehicles. Kat and Noble Six dodge the mortar fire, and turn towards a bridge across a deep chasm, but as they prepare to cross, a plasma mortar destroys the bridge.
Kat accelerates and the Warthog manages to jump the gap in the destroyed bridge, but crashes violently on the other side, (presumably) killing the gunner and sending Kat and Noble Six flying.
Fade to white.
Fade back to Noble Six's point of view, which is hazy. The SPARTAN is lying facedown after the crash, with an M319 Individual Grenade Launcher lying several feet away. Vision clears, and Six glances towards the destroyed bridge. A second Warthog attempts to clear the gap in the bridge but fails, and the troopers inside fall screaming into the canyon below.
Six gets up, grabbing the grenade launcher along the way.
Kat activates her Armor Lock as the Warthog she is using for cover explodes after being shot by two Banshees. A Spirit drops down troops and flies away. A Falcon flies overhead and engages a few Covenant troops before being shot down. On the adjacent plateau across the river, dozens of Warthogs and Ghosts are clashing.
Kat and Six encounter heavy resistance as they move up the hill, including two Fuel Rod Shade variants. After eliminating the enemy forces in the area, a Pelican shows up with a Missile Warthog.
If the player stalls:
Kat and Six drive a short distance before arriving at the AA gun. A Falcon flies above the Covenant infantry, engaging them before being shot down by the AA gun.
As they approach the gun, a furious battle can be seen in the valley below. Three Scarabs and multiple Type-32 Ghosts, Wraiths, and Banshees are exchanging fire with a large group of Warthogs, Scorpions, and Falcons.
Kat and Six proceed to the AA gun, encountering resistance along the way.
Kat and Noble Six eliminate the Covenant troops in the area. Six then goes into the base of the AA gun and destroys its power core. He/she makes a quick exit as the gun begins to overload.
After the AA cannon explodes, three Longswords and two heavy frigates, the UNSC Grafton and the UNSC Saratoga, fly overhead. A Covenant Phantom arrives but is quickly annihilated by the frigates' guns.
The frigates open fire on the Covenant forces in the valley, as the Longswords commence a bombing run on the three Scarabs, destroying two of them and disabling the third, which detonates seconds later.
If the player proceeds without Kat on their Warthog:
Kat and Six proceed on, soon driving under a partially destroyed bridge. They head up the slope, encountering a T-26 AGC Wraith and a group of Skirmishers.
A Pelican, while under fire from a Phantom, drops off a deployable bridge, allowing NOBLE Team to continue.
They cross the bridge and continue down the valley, soon arriving at a mining facility that is across a canyon.
"Hand Over Fist"
The Spartans arrive at a bridge over the canyon. Several Army troopers are under fire from Covenant troops and a Shade turret, which are soon neutralized. The Spartans and troopers advance on the BXR Mining facility.
They move into the facility, encountering resistance as they go.
The Spartans move farther into the facility, eventually finding the Zealot - one of the Devoted Sentries.
If the player eliminates the Zealot:
After eliminating the enemy forces in the area:
Kat and Six move outside to find two Unggoy, three Ghosts, and a Revenant. When Noble Six exits the mining facility, the two Grunts attempt to escape in the Ghosts but are quickly eliminated. Six and Kat commandeer the Revenant (or continue on foot) and proceed down the trail, encountering Covenant forces as they go.
Kat and Six arrive at the second AA cannon and engage a large amount of Covenant forces, including two Wraiths, a Mgalekgolo pair, and a swarm of Drones. A Falcon flies overhead and assists in clearing the area before suffering the same consequence the previous Falcon did near the first AA cannon; shot down by the AA cannon.
If the player takes too long to disable the AA cannon:
After neutralizing the Covenant forces in the area, Six proceeds inside the cannon and destroys the gun's power core. The gun soon overloads and explodes. A Phantom arrives to drop off reinforcements, which are soon defeated.
A Pelican arrives soon after, dropping off troopers.
A navpoint appears on Noble Six's HUD.
If Kat has accompanied the player to this point:
The Falcon arrives.
Noble Six mans one of the Falcon's M460 Automatic Grenade Launcher.
The Falcon flies along the river. It eventually reaches a bridge, with Covenant forces attempting to cross it.
Six eliminates the forces on the bridge. Jorge and Six encounter more resistance further down the canyon, but Six eliminates them as well.
The Falcon approaches a spire with an enormous, visible energy shield.
They arrive at the edge of the shield. The pilot hesitates, hovering just outside it.
The Falcon flies towards the shield and the screen flashes white.
Cuts to Noble Six's point of view as the Falcon spins out of control, scratching the rock wall in the process. The grenade launcher retracts, and Six holds on to the side of the Falcon. Six looks at Jorge, who is also holding on to the side of the Falcon.
The Falcon crashes. Six is thrown a short distance from the Falcon. Jorge emerges from the Falcon, tossing out equipment. Six grabs an assault rifle on the ground and stands up. After looking around briefly, Jorge picks up his gun.
Skirmishers and Unggoy are seen moving downhill towards the crash site.
Jorge and Six move across the river, encountering minor Covenant resistance, composed of only Unggoy, Kig-Yar and Skirmishers. The two Spartans arrive at a small cliff overlooking the base of the Spire as the Spire comes into full view. A Phantom seemingly appears out of nowhere in the Spire's midsection, and flies away, outside the dome-shaped energy shield.
Noble Six eventually makes it to one of the gravity lifts, sending him/her up to the top of the spire.
Alternatively, Six can hijack a Banshee and fly it to the spire's top.
Six arrives at the top of the Spire.
Noble Six eliminates the hostiles in the spire and proceeds to the spire controls.
Six powers down the shield.
The shield dissipates. Six sprints for the outer edge of the top floor, where Carter and Jorge are waiting in a hovering Falcon. Without slowing down, Noble Six leaps off the spire and is caught by Jorge, who pulls Six up into the Falcon.
The Falcon begins to pull away from the spire.
Noble Team's Falcon continues to fly away from the Spire, joining a larger group of Falcons.
The UNSC Grafton, in a shallow dive, moves towards the spire past the Falcon with Six, Carter, and Jorge. The Spartans brace themselves.
The Grafton continues to move towards the spire, and, with a bright flash, fires its MAC cannon, hitting the Spire and shattering it. Jorge, satisfied, turns back and nods at Carter and Six, failing to notice a purple glow illuminating the sky above the Grafton. Moments later, an energy projector beam streaks down from the sky and hits Grafton's bow section, instantly gutting the ship. Secondary explosions blossom along the hull, and the Grafton begins to plummet towards the ground.
The Spartans watch as the aft section of the Grafton explodes. The forward section crashes to the ground.
As Six looks out to watch the frigate fall, Air Control calls in.
Fade to black.
