Event Horizon and FEAR 1... doom alittle bit.. just needs some heavy metal in teh background and its all good 
This, because I haven't played any other "real" horror/ atmospheric games (I don't count Fear, because I was only surprised when Alma decided to play peek a boo with me while climbing ladders).la-le-lu-li-lo said:dead space was the last thing that managed to scare me.
Oh man i LOVED that game! Never underestimate the power of waterguns =PTehCookie said:Zombies ate my Neighbors, its not scary anymore but I was 5 when I first played it and Sega genesis graphics were high quality back then.
