Have the Point Man shoots multiple times at the air vent above the painting of the waterfall in room 56B. The wall in the room will open, allowing access to a hidden area, with Mapes dancing in front of a strange picture. The Point Man can shoot Mapes to kill him.
When first arriving at Interval 05 Malignancy Part 2, there will be a part where you have to crawl through a vent. Continue through the vent until you get to the room past the locked doors. There will be a door with a strange insignia on it. Go through it and you will see a ghost sitting on a photocopier. Wait for a little while and you will see exactly why the ghost was sitting on it.
After Alma Wade's two halves reunite, you can access a secret room in the storage room by entering the ventilation system above a stack of white crates. Smash the spinning fan inside to get past that area. You will find Norton Mape's ragdoll body dancing in a multicolored room with music from Shogo: Mobile Armor Division.
