MAP18: Neurosphere (The Plutonia Experiment)

MAP18: Neurosphere is the eighteenth map of The Plutonia Experiment. It was designed by Milo Casali and uses the music track "Demons On The Prey" from Doom. In its visual theme and architecture, this level is similar to MAP14: The Inmost Dens from Doom II.

Secrets

 * 1) In the central building is a circular blood pool in front of a baron-faced wall. Follow the stairway to the left up, and continue along the path and down another set of stairs. At the bottom of the stairs, do a u-turn left and you will be at a doorway leading outside. You should see a gray brick "railing" surrounding the lower pathway outside. Run onto the top of the railing from the doorway you are standing in and turn around. There is an alcove in the wall just left of the doorway you came from; run into it from the railing to get the megasphere and BFG9000 inside.

Bugs
