Essentials[edit]

Follow the breadcrumbs of weapons and ammo to a small drop. Fall down to be greeted by a glut of enemies: alien guardians sit in the doorways on the left, mancubi occupy the other side, and two archviles are in the corners behind you. Head to the left onto the terrace, and then turn left once more to head down. Be mindful of the various monsters that will appear in the area, including a pocket of cacodemons and alien guardians that open up after you step off the dark stone steps. Make a right and follow the rocky path to a plasma gun guarded by a group of revenants and an archvile that will teleport in after the fact. The steps across hold a megasphere if you need health. Head back to the dark stone steps and walk off the cliff opposite to find the red key, spawning Hell knights, stealth plasma aliens, and revenants.

Head up the stairs directly ahead and use the red key on the door to your left, dealing with more stealth plasma aliens. Walk onto the elevator and turn right at the top to find a path to the blue key. Handle the ambush, being mindful of a sniping arachnotron across the map. Head back the way you came and use the switch in the alcove to your right to open the bars back to the elevator. Go all the way back to the starting vestibule and head through the opposite doorway to a room with arachnotrons and mancubi. Kill them all, then press the switch in the nook across the room to open two areas to the north and south. Deal with more enemies, then use the elevator on the south end to head up to a cliffside.

Here you can go back to the very start if you left ammo or health behind, but if not then you will want to follow the narrow walkway to the yellow key. This will trigger Hell knights to populate the walkway and two arachnotrons on the other side looking down on you. After surviving this fight, walk off the cliff back to the starting area and deal with one more ambush: this time a big group of revenants. Head straight across and up the steps to the yellow door which holds the exit.
