This map was originally made for a project called The Ninth Gate that never saw the light of day. The idea was to create a set of levels inspired by Episode 4 of The Ultimate Doom. But since we never got around to finishing it, we decided to release the finished levels individually. Most of this map was made during 2001-03 using DoomCAD, so the architecture is pretty simple, but detailed. There’s a titlepic replacement made by me, and some awesome music by Damian Lee (except the level music which is from Duke Nukem 3D).

Doomworld selected The Outer Darkness as one of the top 10 levels released inĀ 2007.
