Frankly, this game scared the beejezus out of me when I first played it. I didn't expect to experience such fear as non-stop demons popped out of nowhere. This game is not for feint of heart, although if you like that type of thing and have a good video card I definitely recommend this game, fear = fun!
Like most first-person shooters, after you beat the game that is usually it the Multiplayer attributes are somewhat lacking. But if you are purchasing this game it probably isn't for that purpose. Doom 3 is the good old-fashioned blood bath as intended, for those who enjoy a little-bit of ultra-violence. GET THIS GAME!
