The good people over at IGN FilmForce have done us all a solid by posting a teaser trailer from DOOM, as well as an interview with the man, the myth, The Rock!
They also have a nice bunch of screenshots that you can check out here. That includes one close-up shot of that lovely BFG.
Now keep in mind that you’re going to want to watch the trailer in a dark room because it’s pretty hard to make out some of it, but nevertheless, go get your DOOM on!
