This game has you playing as a tank... but not just any tank, no, this is an indestructible tank! The only weapon you will have at your disposal is yourself - use your tank like a missile to slaughter the waves of enemies that attack you. The longer you end up playing, the more enemies that will come on to the screen at once - leading to some very chaotic situations as you get farther into the game. You'll have to use various approaches to defeat foes... such as if an overhead attack is coming from a helicopter, you'll actually want to let it hit you with bombs, using the force of the explosion to shoot yourself upward and then using yourself like a battering ram against the enemy. Should you manage to get airborne and stay up there you can try and maximize the amount of experience points that you earn by stringing together combos where you hit as many targets as you can before you get back down to the ground.
