Dead Space spoiler
An obvious twist is when you start receiving transmissions from your girlfriend with her saying incredibly odd phrases like "Make us who again Issac". OH come on lady, am I supposed to believe everybody on this f**king ship died but my weakling girlfriend, PL-EASE. This woman is obviously a concoction of my brains self denial.
Then the game did bullshit where she opened a door for me and im like 'Oh wait, she can interact with real things and the Necromorphs attack her? Well either this is a very complicated hallucination or somehow she is still alive, or evil, or something...' and I became confused.
Then the game ends by laughing in my face because it thinks I didn't figure out she wasn't real.
YES I DID YOU F*** C**MPET but you made it physically impossible for that to be the case! I hate developers pulling that nonsense.
*Spoilers*
You spend most of the game hot on the heels of a young couple who have managed to survive this far. It's the young woman singing 'twinkle twinkle' who is actually moving stuff, using consoles, etc, but Issac's seeing his girlfriend. A lot of the audio logs you find are theirs. Eventually her boyfriend is caught and killed by doctor crazy (it's the 'witness the conviction of a true believer! *stab*' bit), and that's when she finally looses it and shoots herself in the head in the room full of candles and bundled up corpses.
*END SPOILERS*
OT:
The game does start with him failing to protect the Empress. Has anyone considered the possibility that the only reason she survived as long as she did was becuase nobody had made a serious attempt to kill her until then? It's possible Corvo really is sharp as a bowling ball.
