The Fallout 3 Mothership Zeta downloadable content hits Xbox and Games for Windows Live on Monday, and Bethesda dropped off the official trailer, in case anyone still needs convincing.

Nothing gets me in the mood for a little retro post-apocalyptic science fiction action-adventure like a little operatic chanting. It worked for the original Star Trek series, and it sure as hell works here. The trailer gives us a glimpse of some of the new toys and outfits we'll get to play with in Mothership Zeta, as whoever we've deemed hero of humanity journeys unwillingly into outer space to save the human race from whatever it is those aliens want to do with us. I'm expecting a vicious probing, but then that's what I always expect.
