There's a DOOM 3 preview on Eurogamer (thanks Frans) offering some fresh first-hand impressions of id Software's upcoming shooter. Here's a bit describing the environment in which the game takes place, showing that the game's Martian dome features the same light bulb glass construction as the one in Total Recall:

Seeing as you're on the hostile planet of Mars, you won't want to puncture the base, unless you fancy a quick death. Hollenshead revealed that if you do happen to shatter one of the complex's windows it creates a vacuum, forcing the area to automatically seal off from the rest of the base. Eeek. And with all the shooting you're going to be doing, what are the chances of not sending a stray bullet through the windows at some stage?
