Beyond the Cimeeon Moon

Beyond the Cimeeon Moon is a 1-player arcade game for the TRS-80 CoCo.

A dead star, a derelict vessel, or is it? Trapped within, you must venture the corridors and defend yourself against the merciless gauntlet of agents of the machine mind. Played from a 1st person perspective, the player must explore 3D corridors in real time, while avoiding enemies. The player can type in commands, and collect items including a rifle and shield. Colored disks can be acquired to unlock specific doors.
