Hall of the Mountain King

Hall of the Mountain King is a Single Player level. The documentation incorrectly states that florescent lights count as Monsters.

This level was released mostly to showcase a Demo involving a fight against some Bots on a single Deathmatch spawn location, resulting in the eventual crash of the game.

Walkthrough
Proceed forward to collect the 2 Cells, Thunderbolt, and Red Armor. Head to the far end and move to the doorway to the next room, then kill the Vore on the far side. Turn around, then return to the starting location and jump on the nearby railing. Look down to kill a Scrag on a platform, then land on the platform. Turn left to kill the Shambler in the Lava, which will also alert the Rotfish around you. Kill the 2 Rotfish in front of you, then turn around. Kill the Rotfish to your left, very close to the platform.
