Play is against other human or computer players. XEvil may be played on one or multiple X displays.
Controls are keyboard or mouse.
However, if you play with the mouse you'll get your ass kicked. The XEvil window is divided into four parts. At the top of the window is a menu with buttons for a variety of options. Under this is the playing field where all the action takes place. To the right are a number of status fields which give information about your character and the game in general while the game is running.
