Whether you're a classic gaming aficionado or you've never hear of PONG, you're in for one heck of a ride with this update on DEFENDER. Based loosely on the arcade original, this version takes place in full-on 3D, offering you six unique ships to pilot through the treacherous, futuristic skies. Employ such maneuvers as barrel rolls, reversals, and loops, dropping smart bombs and other ammunition on the countless enemies. Play alone or battle a friend across the surfaces of Venus, Mars, and even planet Earth.
