This map is built for Infection game types. The house covers almost all of
foundry's open area. There are 6 main parts to the haunted house: northeast
wing, northwest wing, southeast wing, southwest wing, the back alleyway, and the basement. The 4 wings each have 1 entrance which would make it an easily
defendable position. These wings also include many weapons (not too powerful
weapons to make the game fair). The back alleyway has dumpsters which to hide
from the ghost. The alley also has a fun secret I hope you will find (it helps
fight the zombie), but can only be found through teamwork. The basement is
considered the last fallback position but that's your opinion. This room has
many equipment options and a custom power-up to help you fight the ghost. Don't ask me why the mongoose is there, I just like putting mongooses in my maps. This map also has a story line: the "explorers" (humans) venture upon a transylvanian town where rumors and superstition about the haunted house run
wild. You speak to one of the villagers who say the owner of the house died a horrible death and now haunts the house. You don't believe the stories and venture in the haunted house, but what if the stories were true?

here are some pictures of the Haunted House

Also, I have seen many haunted house maps around forgehub, and I have to say they are quite good but I did not copy or steal them from anyone, this map was one of my first maps I made.
