Retroshoot has you controlling a spaceship that is constantly shooting. All you have to do is use the mouse to move your ship around the screen. The screen will start out with your enemies coming from the top of the screen but with every wave you will shift to side scrolling and back. The power-ups are the most fun part of this game. Some will give you a mini ship to shoot with you, while others will send out electrical sparks or a wave of destruction to kill everything on the screen. See how many wave you can make it through in Retroshoot!
