Kyphus

Prototype

Kyphus is an unreleased Atari 2600 prototype from Apollo, programmed by Tim Martin around 1982. It was never sold, and the only known copy of the prototype surfaced in 2006. What survives is an early work in progress: a strange pseudo-3D maze with very little actual game in it, but a rare look at a project that was lost for more than twenty years.

What you can do in the prototype

You guide a small, stocky figure through a maze of rooms drawn in a pseudo-3D perspective. A glowing cloud that fires lasers floats around, and a multi-coloured robot follows you. The maze has 64 rooms, each in its own colour, with exits on the sides and at the top and bottom.

Be prepared: this build has no collision detection, so neither the cloud nor the robot can hurt you, and there is almost no sound. In practice you can only wander from room to room. The odd letters and numbers in the score and lives counters are debugging values the programmer used during development. They show your position, a countdown timer and the room number.

The story behind Kyphus

Apollo was a small Texas publisher known for unusual games such as Lost Luggage and Wabbit. Kyphus was listed in some of its advertisements, which showed a box picture of a wizard fighting evil clouds in a temple. The game code holds a few clues about the plans: the words Protect, Destroy and Invoke, probably commands you would have given the robot, and graphics of a large monkey that may have replaced the robot. The final goal of the game is unknown. Apollo went bankrupt in 1983 during the video game crash, and Kyphus was never completed.
