Drive a single tank against the enemy army. Defend your teleporter and prevent enemy units from escaping through it. Do not leave the battlefield or you will be terminated.
Start with a bi-plane which is mounted with a puny caliber gun and a handful of bombs. As you battle your way in the air through different types of landscapes and environments, earn points to upgrade to a much powerful plane.
Defend the planet from waves of invaders. Kill all your enemies, pick up bonuses, upgrade your tank, unlock new types of guns to deal with the 8 end-level bosses throughout the game.
