Retro Gaming got Micro-sized with the Super Micro Asteroids Keychain Gamer from HyperMegaTech! Small enough to fit on your keys and go anywhere, but large enough to be playable. Features three great Atari games - Asteroids, Gravitar, and Yars Revenge. The 2"" Rgb screen allows maximum playability, along with a volume control for just the right amount of sound, making this more than a novelty. Requires 3x Aaa batteries (not included).
