Mission briefing
According to both the text file and the Infopack:


 * Well soldier, it doesn't look good.. All we've received from the target is a crackly radio transmission, from which we could only discern the fact that the area is *very* dangerous, and if the conditions weren't such we'd arm you with a H-Bomb.  There's not much after this though.. Get past this one and you're home free.. Good luck trooper!

Essentials
Teleport (no return), use the skull switch (medium and hard skills: beware of the arch-vile on the back side), open the skull doors, open the door between the torches (a pain elemental waits for you).

When you go in, the side parts will open. This also means that as soon as you make a noise, additional monsters will teleport in, some of them onto the red cross in your back. Open the door at the other end, beware of monsters behind the side walls and use the green teleport stone (no return).

Open the cross-like wall parts, use the lift to reach the switch behind the cyberdemon, this switch will raise the stairs to another switch, which will open the final arena. When you make a noise or enter the corridor, the demon-spitter will start.

Jump down into the arena and use your BFG9000 for the spiderdemon. Pick up the light amplification visor, this will trigger the pillar behind to lower. When it is down, you will find an invulnerability sphere that you have to pick up because it contains the blue key. While you are waiting, lower the two columns on the left and right, which will give you the yellow and red keys. Use the lift to the central building, switch on the three skulls, direct some rockets at the demon-spitter and you are done.

Secrets
There are no official secrets in this level.

Bugs

 * Each coop-player starts in his own room with an identical equipment (the same as in single-player mode), but none of these items is flagged as multiplayer-only. The equipment per player includes: A chainsaw, a shotgun, a super shotgun, a chaingun, a rocket launcher, a plasma gun, a BFG9000, a box of bullets, a box of shotgun shells, a box of rockets, three backpacks, a berserk pack, a megasphere and a partial invisibility. This means that the triple amount of those items is not available in single-player mode, so one may obtain only 35% items in this map.
 * There are still at least 36 lost souls alive in the map when the last of the three pain elementals is encountered, preventing the pain elementals from spawning any further lost souls and disarming their attacks. See Lost soul limit.
 * The "yellow" key-locked switch (linedef 691) is erroneously flagged as requiring a blue key (linedef type 133 instead of 137,) rendering the yellow skull key useless.

Speedrunning
As this level does not contain official secrets, the NM 100S category is redundant.
