Call of Duty: How to Get All Possible Campaign Endings
SPOILER ALERT: This section includes spoilers for every ending available in the game.
These endings are influenced by the major choices you make during the game. For a full breakdown of those choices (and their consequences), be sure to check out our Choices guide.
If you choose to tell Adler the truth at the end of Identity Crisis, and complete The Final Countdown, destroying Perseus’ base before Project Greenlight can be activated.
This foils Perseus’ plans and stops the nukes from detonating, saving the lives of millions.
Adler will accompany Bell to a second location after the mission is complete, asking Bell to make one final sacrifice before turning his weapon on them.
If you choose to lie to Adler at the end of Identity Crisis, but you don’t use the radio to coordinate an ambush for Adler’s team (either because you choose not to, or because you hadn’t unlocked the back section of the Safehouse yet), Bell will accompany the team to Duga.
Unfortunately, with no Perseus reinforcements to back Bell up, the player will be killed by Adler after confessing to sending the team to the wrong location on purpose.
