Oo-Topos is an interactive fiction game published by Sentient Software in 1981 for the Apple II. In 1986 it was re-released by Polarware for additional systems and with graphical depictions of scenes described by the game's text. The graphics were designed using Penguin Software's Graphics Magician.

Plot

The pilot of a space vessel is carrying important cargo vital to the survival of humanity. The pilot is attacked by space pirates and forced to land on the planet Oo-Topos. After landing the pilot is captured and imprisoned in a fortress on the alien world. The pilot must escape confinement, retrieve the precious cargo taken from the crashed ship and get off Oo-Topos with it in order to save the human race from extinction.

Gameplay

The player enters commands on the keyboard to progress. Commands usually involve verbs such as "Go, Get, Put, Shoot, Use, etc." and nouns such as "laser, food, rod, etc." Directions such as "North, South, East, West" are used to move through areas and rooms within the game. Abbreviations are allowed such as "N, E, W, S." When entering a new area, the text gives a detailed description of the location and any relevant facts that may or may not help with progress. This can include both objects and living beings.

In the 1986 re-release, the drawn-in graphics overlay the text. When actions are performed on objects that are allowed to be manipulated (retrieved, inserted, dropped, etc.), the objects appear on screen as though they had been manipulated or moved. After commands are executed, some real-time actions are drawn-in such as a bright light flash from a laser gun or wearing goggles to "darken" a room.

Reception

Dale Archibald reviewed Oo-Topos in Ares Magazine #13 and commented that "Aside from the fact that you can be resurrected, this isn't a particularly unusual game. If mental jigsaw puzzles are your favorite hobby, Oo-Topos should keep you happily occupied for many, many hours."

Legacy

Many years later, Penguin Software released Oo-Topos (with several other games) as freeware.

Also after end of official support, an enthusiast reconstructed a source code variant of the game's engine to port it to modern platforms.
