Cryostasis: The Sleep of Reason is a survival-horror first-person shooter for the PC that is set in 1981 aboard the Soviet ice-breaker ship, the "North Wind." Powered by nuclear energy, the "North Wind" is tasked with breaking through ice floes blocking Arctic shipping routes and clear a path for other vessels. Suddenly, the "North Wind" shipwrecks near the North Pole and Alexander Nesterov, a Russian meteorologist, is sent to investigate. He finds a ship haunted by dead crewmen who have been transformed into frightening zombies.Official Site: Cryostasis

When first announced, Cryostasis immediately received a lot of attention because it would make use of AGEIA's PhysX processing unit, a fairly new physics technology whose full potential has not been showcased in very many new games.

Initial previews and reviews of Cryostasis have not been very positive. IGN, in a preview written in January 2009, stated that the game was "more than a little rough around the edges" and that, despite the cutting edge graphics technologies used, "it's visually underwhelming [with] sluggish controls, a combat system that's slow..."IGN: Cryostasis: Sleep of Reason Preview (January 26, 2009)

The game is so far averaging a review score of 7/10. PC Format, who gave the game an 83%, summarized their review by saying: "Cryostasis is a beautiful, yet flawed, gem of a game. It offers up a thoroughly unique experience, that at its height is as breathtaking as it [is] terrifying."PC Format: Cryostasis Review (March 9, 2009) PC Gamer UK, on the other hand, came to the conclusion that Cryostasis is "snail-paced frozen nonsense."Metacritic.com: Cryostasis: Sleep of Reason Reviews
