Walkthrough[edit]
Essentials[edit]
Take the shotgun and armor, open the lion door to enter a room with four more doors then open the west door to access a lift. Ride the lift down (a cacodemon is waiting at the bottom on Ultra-Violence (UV) and Nightmare (NM) skill levels) to enter a courtyard, then open either of the gargoyle doors on the west side and go up the steps to a ledge with shotgun guys. Approach the gargoyle switch in the west wall to lower it, revealing a Hell knight (and baron of Hell on UV and NM) guarding a switch that will open the exit door on the other side of the map. Go back to the courtyard and use the tunnel on the north-east side to enter a second courtyard on the east side of the map, then open either of the satyr doors on the east side and climb the steps to a ledge with imps and zombies. When you reach the top, the east wall will open to reveal the exit switch.
Other points of interest[edit]
The central building contains a number of items. A chaingun and super shotgun can be found in the middle area. The two cages on either side of the western staircase hold a megaarmor and chainsaw. The south-west window has a rocket launcher and the north-east window has a plasma gun.
Lowering the lift north-east of the starting point will reveal an alcove with a berserk pack, a partial invisibility, a clip, and an energy cell pack.
Open the door on the south side of the eastern courtyard to find a supercharge (on Hurt Me Plenty (HMP) or lower) along with a megaarmor and computer area map (HMP or lower). Taking the items opens a compartment behind you with a baron (or arch-vile on UV and NM) guarding an energy cell pack, plus shotgun shells and a box of rockets on UV and NM.
Secrets[edit]
- In the central building, walk through the false wall at the north end and run across a gap to reach the ledge on the other side. You can get a supercharge (or a megasphere on Ultra-Violence and Nightmare) and ammo here. Open the eastern wall and grab the BFG9000. The secret sector is the doorway to the BFG9000 compartment, and is too narrow to step on. See Bugs. (sector 211)
Bugs[edit]
The secret sector is a slim doorway that cannot normally be stood on, making it impossible to register the secret without cheating or exploiting even though the secret items can be accessed without issue. The secret can be registered by use of the idclip cheat code, or by luring the arch-vile up to this area, having it blast you into the BFG9000 compartment (being careful to not let the compartment door shut you in, as this will get you stuck) and then using the save positioning exploit to warp down onto the slim secret sector, registering it.
