Secrets[edit]

In the starting area, near the southeast side of the northern rocky nukage fountain that goes backwards, is a hidden switch on a smaller rock that lowers the lavafall in the north part of the area. (sector 66) Behind the lavafall, you can find a rocket launcher, a super shotgun, a chaingun, and ammo for these, all guarded by imps, pinkies, and mancubi.

Bugs[edit]

Facing the central tower that houses the end of the level can cause lag on less powerful machines.

Trivia[edit]

The complex architecture of this level and number of monsters causes performance problems in some source ports due to CPU cache usage, and has prompted some to change their internal architecture to support it.
