Doom 3 is a game with delicious graphics wrapped around an unbelievable story; traversing to hell and back. The 3D surround sound effects make you sit tense on your seat and jump at the sudden attacks that are more common than not.
The Doom 3 levels are very dark, needing you to hold a torch through most of them; you cant hold a firearm and a torch at the same time. The number of levels should keep the most avid gamer playing for at least three days. A decent graphics card is needed if you are to play this game. It ruins the experience if the grapics are choppy or the game keeps hesitating.
The multiplayer features were just a last thought added on and the game does not have much to say for re-playability, but all in all, it's a great game and well worth purchasing.
