soo....basically zombie aliens scare you more than drugged out 1950's scarecrow looking thingies.
you should try fear2 if u want to get scared. Or just turn on a good horror film. I think all of those games are terrible.
To me fear 1 was amazing, and yes it has its scary moments...
but bioshock naah not at all..but then bioshock is not meant to be on the same genre as fear i guess or very creepy games..but its decent though
