Gameplay
After a pseudo-3D view of a temple, the game switches to six side-view rooms inside it, each with its own decoration and colours, where all-black ninjas appear. The doorway at the bottom of the first room leads back outside; the doors in the background cannot be opened. This is an early, unfinished build: there is no collision detection, so nobody can be hurt, there is no way to clear a room, and your fighter walks slowly with no run option. It is a curiosity to explore, not a game to beat.
About this prototype
Black Belt started as Martial Arts and carried the model number CX5231. Programmer Alan Moss Sr., a karate expert, reworked Alan Murphy’s animations so the moves looked like real techniques. In a 1983 in-house video Moss described a game built on martial arts philosophy, where avoiding a fight was often right, with difficulty that adapted to the player, and hinted at two-player cooperation. Internal documents show the project slipping past its 15 March 1983 due date, and the programmer left Atari around then. Builds survive from 23 December 1982, 6 January 1983 and 5 July 1983. AtariProtos says it is unclear whether Atari cancelled the game or had nobody left to finish it; it was never released.
