MAP06: Fistula (PlayStation Final Doom)

MAP06: Fistula is the sixth map of PlayStation Final Doom, and the sixth map of the Master Levels episode. It is based on the PC version of MAP01: The Fistula from the Master Levels for Doom II, with modifications to accommodate the PlayStation's framerate and memory limitations and add enhancements such as colored lighting. It uses the music track "The Foulness Consumes".

The author of the original level was Christen Klie. Changes for the PlayStation port were authored by Tim Heydelaar.

Essentials
Climb the staircase and open the north door (which is actually a lift). Go through it to a room with three staircases, then head east through a gray room until you reach a lift. Take the lift to the bottom floor and head south and west through a corridor of flashing lights, watching out for monsters that teleport in. As you reach the end of the corridor a lift will lower in front of you; step on this left and head south and east through another corridor, which will bring you to a staircase; climb the stairs and open the wall at the end. Go east and carefully walk around the narrow ledge in the next room to the teleport pad. This will take you back to the start area, where you will see that another teleporter has lowered with the yellow skull key.

Collecting the yellow key will teleport you back to the room with the sludge pit. Head west through the gray room and back to the room with three staircases. Go north and open the yellow door in front of you, and take the blue skull key found behind it. Return to the previous room and go west, open the blue skull bars and climb the staircases to the red skull key.

Go back to the starting room and open the east door to get to a dark room. Press the switch in the south-west corner to lower the nearby lift, step on it and head south-west to jump to the bottom of the staircase. Head outside and go east and north around the brick building until you reach the red door. Open it and press the switch behind the door to finish the level.
