Amnesia˜ The Dark Descent
So recently i've been playing Amnesia for my Halloween Spirits 
I've gotta say' this is probably the only game that made me jump out of my seat while playing.... I barely died throughout the playthrough... mostly' Amnesia is very creepy especially at certain moments in the end...(with my volume high up on my mac)

I think now this can be purchased for $10 in US (unsure of amount in € euros)
This game overall is pretty interesting (about 8 hours of gamplay)
Let me know what you think of Amensia(it's alright in my opinion)
If you want a game that will make you sh*t your pants, and not just jump out of your seat, go search Gamestop's used bin for the old PS2 game Fatal Frame II: Crimson Butterfly. That game is perfect for Halloween.
I think I might go play the original Silent Hill at some point tonight, I love those games and it would really put me into the Halloween spirit.
Thanks to SBIzokronus for the fantastic sig!
i've heard about Amnesia, and in all the reviews i've read there is always one certain theme going: make sure to have a big supply of underwear ready.
