OK, so I played this map after 3 years and I saw it was so linear, stupid, simple and omg I hated it. So I changed some stuff, I made this map less boring (more props, less empty rooms), now vents are extended, It's more obvious how to do it in sneeky way etc. I hope, that now this map is finally better

Added train. Fixed buggy wall in new room.

Updated narration. Added zombies at the end of the map. Added new room. Added boxes and other details.
