From the developer:
PongWars combines the game of "Pong" with the sci-fi classic "Star Wars" into a gargantuan game of entirely epic proportions. It features 640x480 graphics and animation, multiple channels of paddle-blasting sci-fi sound, an in-game MOD music soundtrack, and great 1 or 2 player action promising many hours of nostalgia for any 1970's geek.
