Sierra sent us the first screenshots from Battlestar Galactica, an action-packed top-down space combat game set in the universe of the hugely popular sci-fi television show. Players can sign up to defend the Galactica, or play as the ruthless Cylons as they seek to remove the human menace from existence. In the works at Auran Games, Battlestar Galactica will be released in Q3 2007, for PC and Xbox 360.
