It is 1994. The Soviet Union has collapsed and from its buried archives, two researchers have discovered documents alluding to a top-secret military operation deep in Siberia. Journeying to the site themselves, the researchers found an abandoned outpost sitting on top of an old mine. While one of the two delved into the documents and maps in a topside office, the other headed inside the mine… which collapsed, sealing them inside. Now, with only a pick and a radio contact to their colleague on the surface, the researcher has only one goal: Find a way back to freedom.
