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.
The battle of the tanks is on again. In the last encounter, the rebel forces were defeated but some escaped. They have now regrouped and it is up to you to clear the planet of Vermon.
