You're alone in a vector desert crawling with enemy armor. Aim your tank with the crosshair — move your pointer around the viewscreen to steer and throttle, the joystick dial in the corner shows exactly what you're commanding. Click to fire. Enemy tanks and supertanks close in and shell you when you're in their sights; hold out long enough and they'll switch to a missile and helicopter run instead. Landers drift through occasionally — shoot them down for the biggest bounty.
Score enough and you'll earn reserve tanks. Run out of reserves and it's over.
