Cryostasis: Sleep of Reason is a first person horror/action game which puts you in 1968 to the Arctic Circle, Russian North Pole station. The main hero Alexander Nesterov is a meteorologist occasionally caught inside an old nuclear ice-breaker North Wind, frozen in the ice desert many years ago. This steel creature once fought for its life and freedom, but has fallen into an ice trap and all the creatures on its board lost not only their natural look, but a right to die. Cryostasis: Sleep of Reason features a unique system called Mental Echo - the ability to penetrate another character's memory and change the actions taken by the character in the past.

The demo requires Microsoft Vista.
