Cryostasis: Sleep of Reason
Cryostasis: Sleep of Reason is a first-person shooter survival horror video game available exclusively for the PC. The game takes place in 1981 on a shipwrecked nuclear icebreaker called the North Wind. The main character, Alexander Nesterov, is a Russian meteorologist who finds himself aboard the ship and begins to investigate what happened to the crew.
The following weapons appear in the video game Cryostasis: Sleep of Reason:
Mosin Nagant M38
The Mosin Nagant M38 Carbine appears in Cryostasis as "Mosin Nagant 1891". Holds five rounds. Has a long range, medium damage but low rate of fire. A scoped version can be obtained, but it is rarely useful, since the whole game takes place in close quarters. The weapon loads with stripper clips when empty and with loose rounds mid-clip, the non-scoped version loads with loose rounds only, which is correct. Infested crew members often use the non-scoped version.
The Tokarev SVT-40 Rifle appears in the game. A rather implausible weapon to find on an Arctic icebreaker in 1980s since this rifle was notoriously prone to gas system malfunction in extreme cold. This is probably referenced in the game by the rifle having much slower rate of fire than in real life.
The PPSh-41 is the only submachine gun and also the only automatic weapon in the game. Comes with the standard 71-round drum magazine, high rate of fire and moderate damage. When the player releases the trigger (actually the mouse), the gun will still fire a few bullets. Some mutated crew members use a heavily modified version of this gun.
Walther Model SLD
The Walther Model SLD is a German World War II double-barreled flare pistol. It appears in the game as "Walter AC-1940 Signal Pistol". The gun fires extremely hot flares at a very slow fire-rate. Those flares can be used to distract the enemy creatures, because they will move towards the heat source. The fired flares can also be used to warm up and restore health.
AMT Automag II
The short variant of the AMT Automag II pistol (which many players mistaken for the Browning Hi-Power) used by several characters during the flashbacks. This weapon, however, cannot be used by the player. The Automag pistol is a very strange choice, it's not only a rare gun, and it was never used officially by the Soviet Union or any branches within it, but the AutoMag II also was not available until the 1987.
The Degtyaryov DP-27 LMG was to appear as the most powerful firearm in the game, but was cut before the final release for gameplay's balance reasons.
