Metal Tank

Game description:

Assault enemy aircrafts and ground vehicles while dodging and shooting down incoming bombs. After each level, use your points to purchase upgrades in the armory. If you're in a sticky situation and have a nuke (radiation icon in the upper-left corner), use it to clear the entire screen. The white chopper is a friendly aircraft that will drop special supplies, so pick them up. You'll be issued 3 tanks—once you run out it's game over.

Game controls:

Arrow keys Left/Right - To move. Mouse key - To aim / shoot. Space bar - To use nuke.
