I didn't expect that the mission which at first seemed so simple would turn into such a terror. Who could imagine that in this bunker there would be such creatures? The mutants resulted from an experiment which suddenly came out of control and led to irreparable consequences for everybody who was here.

I found all developments of the laboratory at lower levels of the bunker but now I'm facing a hard way to the surface. The main task is to get out of the bunker staying alive and not to become a living dead.
