The game is best described as Pac-Man meets Worms. You basically control a Pac soldier of your choice (including even Ms. Pac-Man!) as he/she runs around the board, trying to kill all other Pac soldiers. The action is fast and fun, although the graphics could be better animated - right now the Pacs look a bit too much like 2D paper-cutout dolls. That's a minor nitpick compared to the fun multiplayer action, though. The game is under constant development, so keep checking the official site for new versions that will hopefully make this fun game even better.
Note: The download here is for Windows 95 and up. You can download other versions (for Linux, BeOS, and MacOS) from the official site.
