An overhead scrolling game (like Gauntlet, but with caffeine instead of food) that lets you play as Tux, BSD Beastie, KDE dragon, A Gnome, A Gnu, the Vi possum from the O'reilly books, Linus, RMS and others.

One can play a single player game against Microsoft, or wage holywar multiplayer network games, such as Linux vs BSD, KDE vs Gnome or Vi vs Emacs.
