In the beginning of Cyrostatis, you start out listening to a story being told to you by the narrator,relayed through notes scattered around a dead body in the snow. You will come across more notes like these later on in the game. The story behind Cyrostatis is that of an old Russian tale whose story is not unlike that of the rise of the ship's crew against it's captain after the shipwreck.
Cyrostatis is set in 1981, and the main character, Alexander Nesterov, is a meteorologist aboard the North Wind, a nuclear icebreaker shipwrecked in the North Pole. Every level, expect for some of your character's flashbacks, Mental Echos and one or two levels set outside in the frozen storm on the Arctic, are set inside the ship. There, there is little light, heat, or anyone to talk to. You are completely alone aside from the zombies that inhabit the ship, and a few dead sailors you meet on the way, whose souls you save by correcting the mistakes that cost them their lives.
The graphics of the game are well done, and the physics, especially that of the water at certain points in the game, are very realistic, and add on to the quality of the game. The mood of the game is one of cold, frozen, darkness. At times, you feel a sense of fear, because at any time, an unseen enemy could jump at you and attack, surprising you, and making you jump out of your seat. Since everything had gotten wet one way or another, many surfaces in-game are frozen, and are a cold gray-blue.
As you progress through the game, you learn more of the story through flashbacks. You also come across many dead crew-mates, many of whom are zombies.. For this reason, you will take any good weapons you can find. This starts out as a simple lock and chain you wrap around your fist, to a bolt-action rifle. You find the lock and chain shortly after you enter the shipwrecked vessel in the beginning of the game, and along your quest you will find a shovel, an ax, and several rifles. You will find a new weapon about once or twice every other level, and after you've found them all, you go through the last levels without any new weapons. At any point in the game, you can select any of the weapons you've already picked up, out of your inventory.
Your first enemy appears right after you get your first weapon; a lock and chain,. A pretty easy enemy to defeat. After several levels, you will start fighting 2 at a time every once in a while, and after a few levels, some much harder enemies. Some enemies are much harder to defeat than others, and sometimes you will fight several at a time. The zombies range in appearance from thin, gray sailors, to stronger, more half-dead looking zombies. Their clothes are tattered, and they look beat up, but very tough, and aggressive. They're easily defeated, as long as you have a way to hit them with your weapon a few times, or fire 3-5 shots at them. Some enemies will take more hits than others.
Eventually, you discover that the ship's captain started down a deadly journey through a part of the see filled with icebergs and very thick ice, ignoring the warning of his first mate, at some point causing the shipwreck. Sometimes you will come across dead crew-mates who aren't zombies. This is where your "Mental Echo" ability comes into play. You use this ability not only to look into the memories of the dead men you come across, but to correct their mistakes, so that they may live. After you correct their mistakes, their body will disappear, and according to tips given to you earlier on in the game, this somehow improves your character.
Another important tool, aside from your weapons and Mental Echo, is your flashlight. Of course, this is used to see when it's dark. Because there are no longer any living crewmen, other than the zombies, aboard the ship, there is little if any light in most areas of the ship, therefor, you will have your flashlight out much of the time. But you will often get the chance to hit a bit red button that turns some light on in your area.
