Players maneuver virtual avatars across a region of cyberspace, downloading computer programs into a 4 by 4 array of memory cells. Programs provide energy and special abilities to the player who controls them. The goal of the game is to be the first player to control 4 programs in a horizontal, vertical, or diagonal row, or to "de-rez" all the other avatars. Game components include a silk-screened cloth board, a deck of 100 cards representing programs, "cyber-creatures," and special actions, and a set of cardboard cut-out avatar pieces.
