Our take on CAT Interstellar

The genre departure is its compact, story-first structure: instead of extending action, adventure, or simulation through a long campaign, it focuses on a roughly 1-hour narrative completed in one sitting.

What is CAT Interstellar?

Play as DOG-VI, a newly activated maintenance bot assisting with terraforming on Mars.

After an accident during the effort, DOG-VI begins uncovering the history of a planet that appears barren. CAT Interstellar is presented as a short story inspired by Robert Heinlein’s The Moon Is a Harsh Mistress. The experience is intended to last about 1 hour and to be completed in one sitting.
