Geometry Wars: Retro Evolved is the sequel to the original Geometry Wars mini-game. If you're not familiar with how the GW concept works, here's a quick rundown. You use the left analog stick on your Xbox 360 controller to fly your ship around the area, and the right analog stick to fire a bullet in any 360 degree angle. Avoid the spawning enemies, and shoot them down for points. You can also pull the right trigger to fire a smart bomb, which decimates all bad guys on the screen. Save these up for when the going gets really tough!
