I made a tough decision - I removed the zombies from the submarine. I don't want the atmosphere of the map to be lost due to zombies. I left them in the cemetery, but in other places I replaced them with people.

Since the map turned out to be quite large and the laboratory had to be abandoned, I decided to remove the extra piece of the map. He shouldn't have been. =)
