HomeLAN Fed has posted an interview about Doom... the board game. Yeah, that's right. Anyways here's a quote to describe what a Doom board game works like:
One player plays the demons and has access to a scenario guide, which tells him how to set up the board and gives him short bits of descriptive text to read to the other players at key moments. Up to 3 other players each play a marine, and they have to work together to make their way through the scenario successfully before the monster player scores too many frags or draws his last card (which means they've run out of time). The board is revealed as the marines move around and explore, and monsters pop up as that happens.
Sounds like a Mars-base version of Heroquest, nothing wrong with that.
