Interestingly, there's no final confrontation with Perseus or his generals. The nuclear detonation is stopped and the day is saved. It seems like all is well, until Adler has a final chat with Bell on a cliff in Solovetsky. There, he thanks Bell for his help (before and after Bell remembered who he was) and then tries to tie up the last loose end of the operation. Bell and Adler pull guns on each other and both seem to fire at the same time. Then the game cuts to black.
