Fly whistling into this universe! Oh, what is this place? It consists mostly of gray, endless mazes of ventilation, corridors, staircases, and corpses. Wait, we have to start at the beginning! Sneak into the room where your enemies are based. They are unusual little men, who have a cross instead of a face. You even found one of them in the trash! You wonder who did it? Have a crazy shootout with lots of victims. Be sure to pay attention to the inscriptions on the walls, which say that in some places you can not use firearms, so get your fists ready!
