MIDI Maze

MIDI Maze is a networked first-person shooter maze game for the Atari ST developed by Xanth Software F/X and released in 1987 by Hybrid Arts. The game takes place in a maze of untextured walls. The world animates smoothly as the player turns, much like the earlier Wayout, instead of only permitting 90 degree changes of direction. Using the MIDI ports on the Atari ST, the game is said to have introduced deathmatch combat to gaming in 1987.

Up to 16 computers can be networked in a “MIDI Ring” by daisy chaining MIDI ports that are built into the Atari ST series.
The game area occupies only roughly a quarter of the screen and consists of a first-person view of a flat-shaded maze with a crosshair in the middle. All players are shown as Pac-Man-like smiley avatars in various colors. Bullets are represented as small spheres.
The game is started by a designated master machine, which sets rules, divides players into teams, and selects a maze. A number of mazes come with the game, and additional mazes can be constructed using a text-editor.
