I dont like games where some freaky retarded mutants are and you have to kill them.
Like you walk slowly, your room is dark and in-game room is dark, suddenly a freaking monster jumps in front of you. That is not my suiting, but offcourse everyone has their own liking, thats just my opinion.
Also, Itar (CZ) , what graphics settings you can turn on and run game good? I have almost same system as yours, but processor is Celeron 2,6 GHz.
