New version of the game of the indestructible tank, where you wait for hits of the enemies to propel you and hit them in turn. But now there's also missiles that can damage you: the blue ones. The game includes a special CO-OP mode, where a second player flies a helicopter and drops bombs on your tank to help you destroy as many enemies as possible.
The game is very CPU consuming, so you should choose at start a quality level according to your computer (the MEDIUM level should be ok). Arrow keys to move to left/right; arrow key up to jump when the 'bomb bar' is full. Space bar to go to the main menu. If you play in CO-OP mode, the second player clicks in the point where you want to place the bombs (usually, over your tank).
