The game Observation is an exciting thriller, implemented in a sci-fi style. The described events occur in the rather distant future, when people were able to settle in space by constructing huge orbital complexes. The plot begins to develop just at one of these stations. One fine day, signals ceased to come to Earth, so the control center decided to send a rescue expedition there. She must figure out what happened on the territory of the complex and why several hundred crew people abruptly stopped communicating.
