In Raid Sweeper, an unkown industrial army is detected on radar. With their planet polluted and no longer able to sustain life, they move en masse to conquer your planet.
Raid Sweeper was a project I worked on as a reminder of the old arcades you used to gather at and play games against your friends, spending all your quarters just trying to get that high score. It's a simple game that can be played in five to ten minutes, and then passed over to your friend for a challenge. Whether or not you decide to compete, you should feel right at home if you've been itching to play at the arcade.
The game can get pretty hard, so don't suck. Please be sure you visit the How to area and the options menu.
