Child of Eden is an anti-shooter shooter. I know that doesn't make sense but once you see the first 15 minutes of the game it will make sense. The basic concept is in the future humans have discovered a way to store store memories. The archives of memories have been infected with a virus that threatens all of the data the archives hold. You must "shoot" the viruses and save the memories. If you don't understand, that's okay. Just look at the pretty lights.
Child of Eden is currently only available for the Xbox 360 and Kinect. In September it will be released on the PS3.
