radar from the top-down view, and avatars from the representation of other players. Despite its number of firsts, the limited availability of the game due to its reliance on specific, expensive computer hardware meant that it was not a large influence on video games or on the modern first-person shooter genre, which is generally held to have started with Catacomb 3-D in 1991 without direct inspiration from Maze. The Xerox version of the game was adapted by Christopher Kent for the X Window System at DEC in 1986 as X MazeWars. This version was based directly on the Xerox source code, which Kent, who had first been shown the game at RAND by Guyton, received from a former Xerox employee. In 1987, MacroMind released a version of the game for the Apple Macintosh titled Maze Wars+, which was playable on the AppleTalk local network by up to 30 players. The game featured five different character avatars, including an eyeball similar to that found in the Xerox version of the game, four different types of robot players, additional maze features such as teleporters, and walls made of lines rather than blocks. Advertisements for the game referred to it as "a direct descendant of the well known M.I.T. and Xerox PARC network classics" and at one point listed it as for sale directly by MacroMind for US$49.95. It was followed by Super MazeWars by Callisto for Mac OS in 1992, which was bundled with Macintosh computers for a time. Several other games based on the Maze concept, with a variety of graphical styles and differences from the original versions, were released in the 1980s and 1990s. These include MIDI Maze for the Atari ST by Xanth Software in 1987, which was ported as Faceball 2000 to the Game Boy, Super Nintendo Entertainment System, and Game Gear; Oracle Maze, a demo application at the Interop 92 conference to demonstrate Oracle's networking technology connecting many different companies' computers; MazeWars for NeXTSTEP by Mike Kienenberger in 1994, and MazeWars for Palm OS by IndiVideo in 1998.
