The SCP-354 is an unusual object which was created in a lab. All scientists who worked on this project were ordered to keep its existence a secret, and if any of them were to lose their secrecy, they would be killed. So you are an elite soldier of SCP-354, and you know nothing about what could be happening in the lab. Your mission is to enter the site and find out what is going on.

You can use various types of weapons, but you should not forget that there is a limit on their use. To kill monsters, you need to get a headshot. If you miss the shot, the monster will kill you, and your death will be a terrible blow to all the scientists. So it is very important to aim carefully.

You should be careful of sudden twists in the storyline.
