- This level occupies the map slot MAP22. For other maps which occupy this slot, see Category:MAP22.
The map requires the player to go through three different areas with different themes and get a key. Once all keys have been obtained the player can reach the exit. The map is large and difficult, as it was originally intended to be map28 for a community project.
Lutrov71 was uncomfortable with implementing the gameplay to the level as he wasn't a very good Doom player at the time, so he got Jimi to implement the gameplay while he mapped the architecture.
