This article is about the campaign mission. For the location, see Nexus (location).
Nexus marks the point of no return for the game, as upon completing the mission, the game will immediately begin The Command Spire, which starts Repository on its completion, and so on. Thus, the player will not be able to do any side missions until after the completion of the main campaign.
Level begins where the previous one left off.
With nowhere else to go, the Chief starts heading downward.
The Chief encounters a Banished squad.
The Chief clears the room of Banished and moves on to the next room, which contains additional Banished troops.
The Chief encounters more Banished.
The Chief fights his way through more Banished, as well as the Harbinger's Skimmers.
After killing all the Banished in the room, the Chief heads down a corridor, up a ramp, and into a room with a window that overlooks the floor below.
The Chief kills these high ranking enemies and continues down a corridor.
The Chief continues his search for the Nexus, battling more Banished, including a Mgalekgolo pair. After a lengthy fight, he kills both Hunters. He then activates a piston, which raises itself and reveals an opening in the floor.
The Chief jumps into the opening and slides down a long winding tunnel.
The Chief lands.
The Chief searches the room he landed in and quickly spots an unlocked door. He heads through it.
The Chief sees a group of Aggressor Sentinels behind a window. One of them scans him as he moves by. He enters the room on the other side and finds himself in a massive open chamber. A deep chasm separates him from the other side. There's also an anti-gravity gondola here.
The Chief steps onto the gondola and activates its terminal. The gondola rumbles to life.
The gondola starts moving, triggering a hostile response from the Sentinels in the chamber.
Multiple waves of Aggressor Sentinels attack. The Chief holds them off long enough for the gondola to make its way to the other end of the chamber.
The Chief gets off the gondola and heads through an unlocked door.
The Chief comes across another deep chasm, but a light bridge activates on its own, allowing him to cross. There are some Aggressor Sentinels here, but they ignore him (even if he attacks them). He crosses the bridge and finally enters the Nexus itself.
She gestures at the Spires around them.
She turns around and spreads her arms out, taking in the magnificence of the sight around them.
She turns back to the Chief.
The Chief doesn't reply.
The Weapon stares down in disappointment. After a moment, she looks back up and gives the Chief a weak smile.
Her avatar dissolves.
The Chief accesses the controls to the gravity lift leading to the Command Spire.

There are three Crucibles that need to be powered up in order to reactivate the lift. The Chief searches adjacent rooms for the necessary power seeds. The Aggressor and Regulator Sentinels in these rooms are hostile, requiring him to destroy them before he can retrieve the seeds.
The Chief retrieves the first power seed.
The memory fades away.
The Chief locates and retrieves the second power seed.
The Chief inserts the second seed into a Crucible, triggering another burst of data. This time the data form the image of his past self.
Cortana appears next to the Past Chief.
The memory dissolves.
The Chief retrieves the third and final power seed.
The Chief inserts the seed into the last Crucible, triggering another memory. The images of the Past Chief and Cortana appear again.
She places a hand on the Past Chief's chest.
The memory dissolves.
With all three Crucibles powered up, the Chief returns to the gravity lift's terminal and deploys the Weapon.
The Weapon gives him a look of apprehension.
She turns around and starts hacking the gravity lift.
The Weapon suddenly vanishes in a flash of yellow light. The Chief looks around for her.

The Weapon stops struggling and turns to stare at the Chief.
The Weapon vanishes in a flash of light, leaving nothing but bits of yellow-colored data behind.
Scene shifts back to third-person POV. The Chief, now seemingly alone, looks around. Suddenly, there's a flash of blue light behind him.
The Chief turns around to find the Weapon standing behind him, fully intact and back to her normal appearance.
The Weapon stares at him in disbelief.
Discouraged, she shakes her head.
The Chief reaches for her, but she snaps her fingers and the gravity lift activates.
The Chief retrieves his now very resentful companion.
The Chief steps into the gravity lift, and begins the ascent into the Command Spire.
