This from the Wikia page on The American Dream (look for the topic "Meeting the President"). With a high Speech skill, you can convince Eden that he is insane, and force him to self-destruct both himself and the base. This check is fairly difficult: even at 100 Speech and 10 Charisma, it's still not guaranteed to succeed, with a 90% chance of success.With a Science skill of 60 or higher, you can argue Eden into realizing his thinking is in fact a fallacy of circular logic, and again convince him to self-destruct himself and the base.If you found Colonel Autumn's room and the ZAX destruct sequence, you can deal with Eden that way (again, blows up Eden and base).You can leave him intact and exit the base. If you choose this option, Level 1 will still function as with the other options; rooms off the main hallway spout fire and the doors become inoperable, and the lower levels will remain sealed. The base will not explode however, and the fleeing Vertibirds will remain intact.
