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.

Walkthrough[edit]
Essentials[edit]
At the starting point you will be attacked from all directions by imps and hitscan enemies. Run south across the first blood moat to the central building for more cover, then work your way around the half-circular stairs to the balcony in the south, where a plasma gun can be picked up. From that spot, you can run across the bridge to the southernmost building where the red key is located. Return to the central building via the same bridge or via one of the four platforms with chaingunners, and find the red door in the south-east corner. Open it, then flip the switch to lower all the red bars on the level.
The north-western area of the map is now accessible via the platform north-west of the central building. Cross the next blood moat and open a door which requires the red key (although it is not marked by red posts). Hit the switch in the northern wall to lower the bars, then go to the circular balcony with the blue card. Exit the building, find and open the blue door in the north, and enter the teleporter. You arrive in the eastern area, where all the way south around the bend, you can jump to a small platform with a skull switch. This lowers the bars to the exit teleport that you passed just before the bend.
Other points of interest[edit]
This level includes plenty of rocket ammo, however, the only rocket launcher present in the level is exclusive to deathmatch.
After lowering the red bars, proceed to the platform north-west of the central building. There, instead of turning left (west) to reach the western building, turn right (east) and proceed towards the ledge, on which there is a berserk pack as well as some ammunition.
Secrets[edit]
- In the central building, go to the western ledge, then turn around. You will see a small room. To reach it, climb onto the step, then onto the railing, then run towards it from some distance away. Inside it is a megasphere and, on higher difficulties, a BFG9000. (sector 61)
Bugs[edit]
A visplane overflow may occur in vanilla Doom or non-limit removing source ports when standing on the easternmost lowerable chaingunner platform in the southern section of the level (sector 87). Additionally, this issue can also occur when standing on the platform with two shotgunners west of the central building (sector 120) or when standing on the platform with a chaingunner south-east of the central building (sector 78), however, neither of those areas are reachable without arch-vile jumps.
