Campaign mode is a means of playing through the game in chronological order, following the story from the side of either the Security or Resistance. Both stories are very different and each side has a drastically different view of the other team. You get bonus missions at the end of each Campaign which are different depending on which side you chose. For the Resistance you get to play the Critical Reaction level and for the Security you get to play a level that takes place in Container City but still has not been named. In total there are 8 missions.
| Resistance | Map Name | Security |
| Day 1: Getting Answers | Aquarium | Day 1: Hostage Rescue |
| Day 2: Breakout | Security Tower | Day 5: Prison Break |
| Day 3: Chen's Plans | Terminal | Day 3: Smash and Grab |
| Day 6: Black Box | Resort | What-If: Chopper Down |
| Day 7: Attack on CCity | Container City | Day 4: Dirty Bomb |
| Day 8: Airborne | Refuel | What-If: Grand Theft Aero |
| What-If: Operation Babel | Shipyard | Day 6: Early Launch |
| What-If: Critical Reaction | Reactor | Day 8: Fallout |
One of the chief things about the campaign is the lack of story or character development that occurs within. Each side of the campaign follows some nameless character models as they discuss the problems with either the Founders (The Security) or the "Terrorists" (The Resistance). The Resistance members talk about how the Founders cut off their supplies, ration their water, and treat them like slaves. The Security members talk about the Resistance as terrorists who are agents of destruction and harm and who will do whatever it takes to further their own goals. The player character is always a background member, never directly participating in any conversations, and has no speaking roles throughout the entire campaign.
