Resident Evil 4 scared me because
a).I thought I would be completly surrounded and overwhelmed
b).I though I would run out of ammo before I killed all the enimies.
There was a really old game, Trespasser, that scared me really bad. That game is known for its horribleness, but i love that game. It has a great atmosphere, and the enemies are terrifiying. Plus it was really hard to shoot and aim, so the game was pretty hard.
Resident evil 1 remake scared me because
a). The camera angle always hid enimes
b). Enimies take lots of bullets, yet you barely find any. You usually have to run.
c). There were lots of startling moments, especialy with the hunters breaking down doors.
Silent hill 2 was the scariest game I have ever played though.
