Avoid the spawning enemies, and shoot them down for points. You can also fire smart bombs, which destroy all bad guys on the screen. Save these up for when the going gets really tough!
The more bad guys you kill, the higher your score multiplier goes (2x, 4x, etc.). The higher your multiplier, the more you can score. But don't die, as you lose your multiplier and have to build it up again from scratch!
Addictive "just one more go" gameplay, with mesmerizing graphics.
Pixel perfect recreation of the Xbox Live Arcade game.
Support for keyboard, mouse, and dual-stick gamepad play.
