This game is a space-aged flight game that pits you against a myriad of enemies. Each level is more and more difficult, but between each level you get the opportunity to upgrade your ship in order to fight enemies that get much harder. Use the mouse to maneuver the ships around and shoot your guns with the left mouse button. You also have torpedoes that can be launched with the space bar. Be careful though, because you can and will overheat if you overdo either of them. You wouldn't want to be without a weapon during a dogfight. Go get em and have fun!
