A separate deathmatch area exists outside the main map.
Pick up all the goodies in the starting room and jump down the bloodfall. The bloody floor is not damaging, so feel free to walk on it. Pick up the BFG9000 on a platform in the middle of the room. Go towards the opening in the wall.
You will be teleported to an area with pillars and arch-viles in them. Go straight forward and the wall in front of you will lower revealing some lost souls. The Gatekeeper is covered and protected by a cyberdemon, which you need to kill.
Drop into the circular pit in front of the cyberdemon. Use the switch on the right. Then use the switch to the left which will lower the pillar in the middle of the circle. Wait until the pillar is nearly at the top and fire a rocket into the brain of the now unguarded Gatekeeper. Fire at least three rockets at the brain, just like in Doom II. The monsters around you may be ignored for the most part.
Other points of interest
If any of the spawn shooter cubes spawn a monster at the player's coordinates, the player will be killed by means of a telefrag. This will happen even if the player is invincible by means of cheats or powerups.
There are no official secrets in this level.
- Just like in Doom II MAP30: Icon of Sin, you can use the idclip cheat code to enter the boss brain area, though it does not count as a secret.
- Similarly to the "secret" above, you can use the idclip cheat code and look around. After a while, you should find several dark rooms, all containing a weapon of some sort.
The two first cases apply to the Icon of Sin and are thus true in any level that has one.
- If the player remains in the level for a long period of time after being detected by the monster spawner, the level will fill up with monsters. If many monsters populate the level, it can cause a possible crash due to the nature of the Gatekeeper that endlessly fires its spawn shooter cubes that turn into monsters when reaching any given surface. The possible crash occurs when the number of living monsters exceed the limitations.
- Savegames have specific problems in the level. If the player saves a game after having woken up the final boss, quits the program and then returns to load the savegame, a Venetian blind crash will occur. A detailed explanation can be read here.
- In the deathmatch area, in the lowest part of the automap in the area with the stairs, it is possible to get stuck behind one of the corpses.
- Some items are in the deathmatch area of the map, that cannot be accessed without the idclip cheat: all five berserk packs and one of the three megaspheres. So it is not possible to obtain 100% of the items. Some weapons are affected too, see the table below.

The pillar from where the player can make his triumphant attack, before the cyberdemon that guards the Gatekeeper.
As this level does not contain official secrets, the NM 100S category is redundant.
