The Mansion is a fairly small map that consists of a bathroom, a lounge with a large table, a closet, and a computer lab. The mansion seems to be owned by either Loleris or Nikilis. There are a fair amounts of hiding spots and the map has a fair size. So this map seems to be equal in whether it is hard or easy for murderers.
This map has been discontinued in 2017; being replaced with Mansion 2.
Mansion 2 is basicly the same map except some of the rooms have different things in them. The bathroom is different too. There are also quite a few more hiding spots.
