The beets are invading! The beets are invading! In Killer, it's up to you to kill all of the killer beets that pop up on screen. Be careful as they appear randomly, and leave just as quickly. Use the mouse to click away evil, and save the world. As well as get a high score. But don't be too slow in clicking them away, or it's game over.
