Started out as a challenge by bps, to build a christmas themed dmm4 map in three hours. In exploring architecture, lighting and textures lurq missed the three hour mark but had it done in three days.
The map is heavily inspired by a real hotel (which name is now forgotten) and the Overlook hotel from The Shining.
Beyond dmm4, it includes a secret single player mission...
