InSomnia is a dystopia carried out in a murky, retro-futuristic style. The game takes place on a colossal, semi-deserted interplanetary space station. Having left their dying planet behind, this space metropolis, along with its inhabitants, has been moving towards the distant, ghost-like Evacuation Point for the past 400 years, where the descendants of the once great people hope to start over the history of mankind.
