From Cpnn
Astro Barrier is a mini-game found in the Dance Lounge. Next to it there is Thin Ice.
Where to find it: In the Lounge on top of the Night Club (arcade machine)
Object of game: You must shoot all the moving targets.
How to play: Press the left and right arrow keys to move your ship. Press the spacebar to shoot. If a target is hit, it becomes a wall, making it harder to shoot the other targets. (Be careful! You have limited bullets!)
