During the course of Utopia, The Guardian descends into the New Pacific Arcology to search for a Golden Age CPU to crack intercepted Cabal communications. The communications reveal that the Cabal's star killing superweapon, The Almighty to be in orbit around our Sun, prompting requiring an urgent reunification of the Vanguard and an assault on the Almighty before it destroys the entire Solar System.
The Guardian moves towards the New Pacific Arcology
While in the Solarium the Operating System will continue on the loudspeakers, saying:
The player continues into the Arcology.
The terminal display has now changed from its earlier screen reading "Welcome to New Pacific Arcology" in English, Chinese and Russian, to showing a schematic map of the Arcology's "Network Layout" identifying the CPU's location and describing the CPU as a "Quantum Core" in all three languages. In the bottom right of the screen the display identifies the Operating System version as OS 118.16
TM-FH-2 is also nearby, next to the doorway to head further into the Arcology.
The player continues through the door into the hallway beyond where they encounter a Wizard and more Hive exiting a now permanently locked door besides a giant hole in the floor, and Ghost Scan TM-FH-1:
The player kills the Wizard and its compatriots.
The player enters the hole and proceeds through the dark nest below
The Hive have already heard the player's approach and attack them, led by a regular Knight equipped with a Cleaver. The player defeats the Hive, continuing on to where they encounter a Shrieker. The Shrieker is defeated and the player continues on into another room, where they fight more Hive.
The player continues on, jumping through some elevator shafts, and access shafts, with Hive membranes or destructible metal grates blocking their path on occasion. As they continue, the environment becomes darker and more claustrophobic. Thralls ambush the player at several locations throughout the tunnels.
Ultimately the player reaches the CPU room, which they drop down into from an air vent in the ceiling.
The Guardian picks up the CPU
The player is ambushed by several dozen Hive on either side shooting at them, forcing them to flee with the CPU. Once picked up the CPU cannot be put down, leaving the player in a third person mode where they cannot shoot back or even melee with the fragile CPU. The player escapes the CPU room.
In the next room are modified Drake Tanks that the player can enter with the CPU and drive.
The player then escapes through the Hive colony in the tank, ramming through the numerous Hive secretions, materials and troops in their way as they drive to the center of the Arcology.
The player reaches the center and proceeds along a long bridge to the landing platform where Holliday's Hawk jumpjet is waiting for them
The player reaches Holliday
A planet before a sun. The camera zooms in and comes around slowly while the music's drums beat with dramatically in the background. As the camera draws closer we can see the planet is wrecked, cracked open by gigantic continent spanning fissures through which the planet's molten core can be seen.
The camera passes by the planet and its debris, as the Almighty comes into sight along with a flotilla of Cabal Warships. The Almighty is siphoning planetary material from the one end, and injecting a bright blue stream of ionised plasma into the sun out the other end. The camera focuses in on the beam, tracking it as it burns through the star's photosphere, generating a massive magnetic disturbance visible in the rapidly spreading sunpot.
The star destabilizes, the Almighty stops firing its weapon, and teleports out of the way of what comes next.
The Almighty vanishes, leaving nothing but a giant black sunspot from the destabilisation of the star's magnetic fields. The camera starts moving backwards, back through the planetary debris
The planet is gone, harvested by the Almighty before its departure, with only a few planetismal sized rocks left where it once was.
The star implodes -
- and explodes in a supernova.
The supernova explosion spreads, wiping out the first planet, as well as all other planets in the system.
The camera zooms out from the distant explosion while a Cabal march picks up in the background. The camera zooms out and begins to shift towards our own Solar System
The scan focuses in on the Traveler.
The camera passes by Earth to look at the Sun in the distance
