actually Doom³ isn't my cup of tea,but i still like it.it's very brutal levels are hard and monsters are strong and weapons are almost all weapons are not strong only two weapons are real killers Doom³ is better Quake i think.Graphics is good.i have always liked Doom and Quake and Blood more than Counter Strike.it's without a doubt pretty scary horror game i think.A demonic invasion at Union Aerospace Corporation's Mars Research Facility has left only you and a handful of survivors with the chance to fight your way to safety. actually Doom³ is scariest game of all time i think.When you first play Doom³ you certainly get a few shocks.
