Resident Evil 4, it was scary shooting off a zombie's head and having a las plagas errupt from the shoulders. and that amazing boss which would dodge your bullets, and you would have to cryogenically freeze it with the cannisters.
that game was absolutly amazing, however notable mention goes to Dead Space, which actully has better controls and is also very enjoyable. if only Capcom didnt ruin RE5....
oh and i think Bioshock was actully quite scary as well, but i didnt enjoy it as much as the other 2.
