EuroGamer has a new DOOM 3 preview, based on a recent demonstration of the game at the recent Activision Activate event in England. Just impressions though, no new screenshots. Meanwhile HomeLAN Fed has some quick impressions of the DOOM 3 multiplayer demo on display at QuakeCon.

The Beserker power-up allows you to use your fists as a one-shot (one fist?) one kill weapon against your opponent. Your vision in the game becomes blurred while you have the Beserker power up and you hear yourself scream as well, which is rather bloodcurdling but very effective; it makes you sound like a banshee. The visual effect on your character as others see you is a set of red rings around your character.
