An anonymous reader writes "Actor Brad Hawkins has been tapped to do motion-capture work for Doom 4, and revealed that the game features the military and civilians fighting side by side. Does this mean the game is set on Earth for sure? GGL Wire has an interview with Hawkins and a selection of production shots. '[Filmmaker Mark Bristol] was very specific on the civilians having a certain personality and the military characters having a separate one as well. The body language of the civilians is less, well, "trained." They carry their guns in a looser fashion and are a little sloppier when they run, a little more freestyle. The military characters are sharp as razors, with very swift moves, exact hand positioning and can turn on a dime.'" This follows news from last month that British novelist Graham Joyce was brought in to develop the story for the game.
