This article is about the campaign level. For other uses of "Exodus", see Exodus (disambiguation).
The level opens with Noble Six, having fallen from orbit in the conclusion of the previous level, waking up on a mountain range and beginning his/her journey to link up with UNSC forces. On August 23, 2552, after wandering through the wilderness, Six arrives at New Alexandria, Eposz, which is under siege by four Covenant corvettes. Noble Six then finds his/her way through the city and links up with Army forces to assist in the evacuation of Traxus Tower, while fighting Brutes for the first time during the invasion. However, they arrive too late, as one of the corvettes has already moved into position on top of the tower.
Noble Six then acquires a jetpack and joins a group of ODST specialists known as the Bullfrogs, enacting an emergency plan to capture an executive landing pad. Six then proceeds to Traxus Tower, where he/she, several Army troopers and the ODSTs take the landing pad, allowing a group of civilians to evacuate in a Pelican.
Noble Six then rides in a Falcon to provide air cover for evacuation crafts leaving the city. They take an alternate route to avoid the Covenant forces clustered in the middle of the city. After an evacuation transport is shot down by a corvette, Noble Six assists Army forces in clearing the way to missile batteries further in the city. The missile batteries disable the corvette's weaponry, allowing the remaining transports to slip past and escape into orbit.
Noble Six is alone on a snowy mountain range, holding his/her injured left arm. He/she slowly limps back to the discarded Reentry Unit to acquire a pistol. The Spartan cocks the pistol and turns around to look up at the remains of the Covenant Supercarrier that Jorge-052 destroyed, now lying shattered on a nearby mountain. Debris continues to plummet into the atmosphere, creating an artificial meteor shower. Displaying a noticeable limp, Six begins to walk away down the mountain.
Fades in. Noble Six, now in a more temperate landscape, jogs up a hill, having recovered from the limp. He/she stops at the top, and the city of New Alexandria comes into view. Three Covenant Corvettes dominate the skyline of the burning city. Smatterings of anti-aircraft fire and explosions fill the sky, and the sound of intense combat is heard in the distance.

Six lets Jorge's dog tags slip slightly from his/her hand and places them in a chest pouch.
Cut to a building's rooftop. Occasional turret fire can be heard in the background. Six, still holding the pistol, creeps beside the edge, jumps down, and staggers slightly on his/her injured leg.

Switches to Six's point of view: He/she lands safely on the Boardwalk and looks toward the road up ahead.
