Description:

Who says a tank driver doesn't need a brain? Put some thought into your shooting!

Instructions:

Destroy all tanks, matching the color of the shot to the tank being shot. After buying upgrades, you can collect energy from the tanks you shoot. Once you've filled a color's energy bar, you can use it (with Space) to send out a laser shot.
In Rampage Mode, there are no colors or upgrades, just 1 life.
