It's not a Cryostasis game, it's an 1C bundle thus it's not 13p but 40 points. It should inclide Death Track: Resurrection, Cryostasis, NecroVision, Death to Spies, Death to Spies: Moment of Truth, NecrovisioN: Lost Company
Either it's a incorrect giweaway or we'll get bundle.

Cryostasis has been removed from the store for individual purchase. At the moment, the only way to acquire the game through steam is to buy the 1C Action collection. Speculation is that 1C has lost the rights to publish Cryostasis. If that is the case, then the 1C action collection will soon be removed (or altered) as well.

I'm not sure why the entry point cost has switched over to the action collection. Usually when a game is removed from steam, Steamgifts retains the last known price of that game as it's entry cost.
