XEvil is a free software platform arena game first released by Steve Hardt at M.I.T on July 26, 1994 over the Project Athena network. Structured as a free-for-all deathmatch between a wide variety of characters with differing traits and abilities, players are pitted against each other or computer controlled bots. Described as "one of the most graphically violent games ever made", the game's website features a tongue-in-cheek disclaimer over its potential offensiveness. Originally developed for Unix systems using the X Windows System, it was later ported to Microsoft Windows systems using DirectX featuring sounds and music. Both versions were released under the GNU General Public License on January 18, 2000.
