I went for the evil ending, that is, explode Talos I and erradicate the Typhon while watching from the chair.
Just to find out they were doing the reverse of what the game makes you think most of the time. During the game you think you're Morgan Yu, shifting / mutating into a Typhon, but what they are actually doing is the opposite. Trying to make the Typhon, you, the player, more human, thorough the decisions you face along the game. Really neat twist I gotta say, which is culminated by the join humans to save their race or finish them for good.
