Which game has the best/most surprising/unexpected...(MAJOR SPOILERS!!!)

...plot twist?

Please DO NOT post details about the plot, just the game name, because we do not want to ruin it for those who have not played a certain game yet (including myself)

Thanks!

Mine has to be: Deadly Premonition, Bioshock 1 and Condemned: Criminal Origins

Finding Nemo...j/k

KoTOR or parts of Bioshock

Bioshock is a good choice, maybe Red Dead Redemption

I think we're gonna hear a lot of Red Dead Redemption.
