I just finished the game.
Spoiler:What a great ending. It caught me totally by surprise the first time I played the game. Though I knew what happens, the replay was still full of discovery. I paid more attention to the details and how the story leads you to believe that the Nemesis is evil.
I took the time to play through some other endings - all resulted in death (along with some good sarcastic comments
). I also went through all of the easter eggs I could find. The only one I couldn't get to work was the '4 skulls film' (clicking on the piece of metal beside the skull crusher in Kaine's torture chamber). If anyone else has seen it, let me know what I missed.
