You are controlling the Array Proximity Shield, use the mouse to control where it is pointing, try to survive for as long as you can Post your highscores in the comments to let me know how far you got!
You are the last defender of the arc array under siege from a wild meteor storm that blew in from deep space, protect the array! The game gets incredibly hard after the 200 point mark, as the scaling of the level is low enough that the meteors are flying and spawning rather quickly, but I see it as a fun challange.
