As a robot you attack from the ground, but spaceships are firing at you from the air. It's important not to get overheated! Meanwhile all kinds of scorpion-like aliens are coming at you. Eliminate them by shooting at them. Try to destroy the space station and to conquer the planet!
Use the left and right arrow keys to walk and click to shoot. Press the spacebar or the down arrow if you want to move or fight faster, with a 'nitro'.
