To celebrate the debut of the final season of Battlestar Galactica, Sierra has halfed the price of the BSG-themed game with the same name, now available from Xbox Live Arcade. You will be able to get the game for just 400 Microsoft Points, but hurry up, as the price will be changed back to 800 Microsoft Points in aproximately 24 hours. Battlestar Galactica is a 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.
