Ur the last best hope for the Tank people. A race of tanks that has lived in peace for eons. This peace has finally been broken by the evil Retro aliens from the Aie-tees galaxy (one galaxy up and to the right from ur own).

It’s up to u to stop these fiends from taking ur world, ur tank wife, ur tank children, from taking everything that means anything to ur armored brain. Do u have it in u to shoot them in this defense shootem-up game thingie? Well doo ya??

These aliens are insidious. They have a special defense that makes random shooting pointless. U need to use ur custom white bullets for the white aliens and even more custom black bullets for the black aliens. Fail to use the correct bullets on the aliens and they will grow stronger!

Stop this alien horde and save the tank race from annihilation.
