"Stop the KVA from triggering a meltdown at a U.S. nuclear power plant."
— Level Description

Fission is the fourth campaign mission in Call of Duty: Advanced Warfare.



At Atlas HQ, Gideon, Joker and Mitchell celebrated a job well done while watching the highlight reel. Irons later entered the room and the four men raised a toast. Mitchell commented that KVA is getting better everyday. Then at the reactor a meltdown begins.

The KVA attack the Vekron Pacific Reactor, calling Atlas' team Bravo to go in and stop them. Gideon briefs Mitchell on their objective as they deploy in Seattle. Explaining the critical nature of the facility, Gideon jokes of Korea's radiation before fighting. Mitchell picks off a few enemy soldiers and ziplines to the ground; during the fight, a hijacked Titan comes in and is destroyed with a Stinger M7. Mitchell optionally can get in a MT to push through the swarm of KVA or use the Mobile Barricade.

When the group enters the facility, Prophet reminds them that the reactor's temperature is climbing and the indicators are below normal rate. There, they encounter and terminate dozens of KVA troops. The team then boards an elevator that takes them to an engine room filled with soldiers. Joker places a cover shield as Mitchell uses his assault drone to eliminate all of them, clearing access to the control room.

Going in, Carter is mortally wounded when he takes the full force of the explosion from the rigged door. Gideon attempts to rectify the situation, to no avail. The group is forced to make an escape as the facility suffers an enormous meltdown. When a cooling tower topples down, Mitchell is momentarily disabled as Joker screams of Carter's demise, but Gideon arrives in a VTOL to evacuate them.

  1. Stepping out of the elevator down inside the ruined facility, turn right and then enter the larger room where the “Follow” marker is visible straight ahead, but don’t continue yet. Stop and enter the interior windowed room to the right of the main path. Look behind the shelves, near a fallen table next to a glowing blue monitor display.
  2. Finishing up the drone control section, you’ll need to move through a curved turbine room. Look under the platform between the first and second turbine. The intel is on some generator unit-looking things behind the pipes.
  3. Leaving through the massive open vault door, you’ll reach a garage with stairs leading down, but don’t go downstairs yet. Look on the catwalk to the right and follow the path to a spool of metal with the intel.
"Above ground nuclear power facilities have been a tactical hazard since their inception. In 2048 Atlas submitted a lengthy report to the Defense Department on the security risks. I guess they didn't like the findings because they buried the report. I think they gave us the security contract just to shut us up. But that's not why I accepted the job. I took the contract because Atlas would give the tax payer the best return on their buck. We spent millions on concrete reinforcements, we built anti-aircraft defenses, but what is our greatest achievement? Eliminating human error. You can build your defenses as strong as you like but the human race is the weakest link in any system. When an attack does come - and I no doubt it will - then mark my words, it will be because someone has left the door unlocked. You can't protect what you can't control."

  • In the opening cutscene, a video of the previous mission shows the Atlas team wielding different weapons (HBRa3 for Mitchell and Gideon, and SN6 for Joker) from what they actually used in that level.
  • The third-person model of the RW1 found near a dead security guard in the lobby lacks the pistol grip.
  • KVA submachine gunners are only found in the beginning of the mission on surface level of the nuclear reactor plant in limited numbers, while shotgunners are no where to be found. Leaving most KVA soldiers in mission Assault Riflemen.
