This is a side-scrolling game for Linux. It is possible to play alone or with other people over a TCP/IP network. If you like to program in C (maybe C++), you may want to write robots that control characters in the game, playing against and making teams with other players or robots. There's also a map editor to build new fight scenes, and you may download a GIMP plugin to be able to read and write images in the game format.
