Map 18: The Courtyard

From your starting position, shoot the lion head on the wall to access the outdoor area.

Defeat the Zombieman, Imps, and Spectre using your Super Shotgun or Chaingun from the safety of the starting room if possible.

Collect shotgun shells and the Shotgun from the stand behind the Imps, and an Armor vest near the door.

Warning: Do not fall into the inescapable slime pool to the south.

Enter the courtyard to the north, eliminating Spectres at the threshold.

As you enter the open area, deal with the Demons to the right.

Run around the perimeter to lure out more enemies from other sections, causing infighting among Imps, Demons, Hell Knights, Cacodemons, and a Mancubus.

Circle strafe the outer area to avoid damage and conserve ammo, picking off remaining enemies.

Collect Health and Armor Bonuses lining the center column.

Note the Invulnerability Sphere inside the center column, but save it for later.

To the west, step on the wooden flooring with pillars. A small stone building to the north will open, revealing Hell Knights and Revenants.

Use rockets or plasma bolts to defeat them.

In the first small enclosure on the wooden floor to the west, collect half a dozen Stimpacks and four rockets.

Continue along the wall, grabbing two Medikits.

Head through the next opening with ivy-coated walls.

Proceed slowly along the passage, shooting Imps and grabbing ammo.

Turn right around the bend to find the BFG9000 [SECRET 1/4].

Warning: The way in will seal off upon claiming the BFG.

Defeat the two Cacodemons guarding the BFG.

Hit the green switch behind the Cacodemons to reopen the exit.

Backtrack to the wooden-floored area and head north to the staircase in the courtyard.

Before ascending, find the Yellow Skull Key hidden in the corner to the left.

Go back to the stairs, turn right, and head along the flesh-colored structure.

Enter the opening in the stone wall to find an alcove with a box of rockets, a box of bullets, and a small cell ammo pack.

To the right of this alcove, enter another wooden-floored area towards the Invulnerability Sphere (do not take it yet).

Defeat the Hell Knight waiting around the corner to your right.

Hit the green switch the Hell Knight was guarding.

Warning: QUICKLY run back to the ammo alcove.

The back wall of the alcove will lower, revealing a teleporter. Step into it to reach a secret room with two Boxes of Rockets and three Medikits [SECRET 2/4].

Examine the gargoyle faces in the corner of the secret room to lower them and return to the courtyard.

Backtrack to where you killed the Hell Knight and flipped the green switch.

On the '+'-shaped building (visible on the Automap), punch, chainsaw, or shoot the lion head on its south side.

This opens a wooden-floored room with several Cacodemons. Defeat them all.

Collect the ammo inside: a box of bullets, a box of shells, and a box of rockets.

Step back out. To your left (east wall), find another opening leading to a small room with Stimpacks and a Rocket Launcher.

Head back out and continue along the eastern wall to find a door leading to an ivy-coated room with a Berserk pack.

Warning: An Arch-Vile plinth will rise to block your exit when you grab the Berserk pack.

Examine the south-east corner (with a different wall texture) to find a hidden door leading into a narrow passage.

At the end of the passage is a room with glowing floor and ceiling.

Defeat the Shotgunners and Demons using your Super Shotgun, Chaingun, and/or Plasma Gun, or use Berserk-enhanced fists for the Demons.

Be cautious of enemies waiting at the end of passages.

From the passage you entered, head straight ahead to the east wall.

Dispatch more Shotgunners around this area.

Access the skull switch on the left on the blue wall to reveal a secret enclosure with a Chain.
