Professor Anton Pavlovich Sokolov, a distinguished military biologist, was appointed the head of a secret military base to maintain the combat power of the state after the end of the Cold War. Under his leadership, a team of advanced scientists was assembled to develop biological weapons. Despite careful employee checks, sabotage occurred on the base. In one of the sections, there was a leak of an experimental sample. The security system instantly blocked the exits and sealed the doors for twenty years... Now you have been thrown into a mission to retrieve the experimental sample. The mission must be completed at any cost.
