Kyphus

Only one prototype of Kyphus is known to exist. It is thought that in the final version of the game the player would have a weapon of some type to shoot at the cloud and robot, but the object of the game is still unclear. A picture of the box was shown in a few Apollo advertisements. It appears to show a wizard battling evil clouds in a temple which is fairly close to the gameplay in the current prototype.

Hidden in the code are three words: Protect, Destroy and Invoke. It is thought that these are commands the player would give the robot to make it do certain things. Also hidden in the game code are graphics for what appears to be a large monkey that would have replaced the robot. It is currently unknown how the monkey would be used in the game, and there is no way to trigger it in the current prototype.
