While the last mission of the so called good ending is most likely the canon one when compared to the other conclusion, it is not fun and feels like it comes from a different game. It starts with a cutscene of Adler and President Reagan reminding Bell how they are fighting for our freedoms, and then you set off into a haphazard war zone. For a secret terrorist organization, Perseus sure can make a lot of noise. To unlock this mission, players have to side with Adler and tell him the truth about Perseus' location.
