Best played in the dark, turn up you volume! Zombie Survival, the creepiest thing ever! Play on hard, moody lighting, small render distance, particles minimal so you don't see the spawners, the zombies will break the doors but if you pick a door up please do not replace it, and do not lock yourself in the room with the iron door. This is so creepy! Please give me feedback and tell me what I can do to improve the map. Good Luck, your gonna need it! :D Heres a hint on where the lever is: look downstairs by the laptop.
