''Microcosm'' is a video game published by Creator/{{Psygnosis}}, released on PC and Sega CD. It was heavily advertised to being a game that verges on being both a fully interactive video game with Hollywood-style visuals and an interactive movie with the play-ability of any video game. The PC version especially makes sure to advertise it very well, as well as make it's packaging stand out broadly (a square donut-shaped box with the game in the middle). If you persevere past it's marketing and it's attempt to sell itself to your face, you'll find that it's a bad to mediocre RailShooter similar to ''StarWarsRebelAssault''. On top of being frustrating, it is littered with poor design choices and eventually fell into obscurity.

The game later received a pseudo-sequel in the form of ''VideoGame/{{Novastorm}}''.

!!Microcosms contains examples of:
* AllThereInTheManual: Every piece of information about the game's back story, along with [[PlayTheGameSkipTheStory so much unnecessary information]] that it is just as long as a couple short stories. Both PC and Sega CD versions.
* FullMotionVideo
* MST: Courtesy of ''WebVideo/TheSpoonyExperiment'' in a full review.
--> "If your movie is worse than ''Film/{{Stealth}}'', you got problems."
* NonStandardGameOver: If you fail the chase level by not shooting down the renegade ship in time, it will go to blow up the CEO's heart, killing him and failing the mission, regardless of how many lives you have left.
* ReformulatedGame: The 3DO/FM Towns Marty, Sega CD, DOS and Amiga CD 32 versions have different level design and assets.
* OneHitKill: The second phase of the final boss has an instant kill move.
* TechDemoGame: The mixture of FMV backgrounds with overlaid sprites was the game's main selling point.
