Essentials[edit]

Collect the shotgun in front of you then continue north, going down some curved steps to face a pair of shotgun guys. In the next room, kill some zombies and imps then head round the outer ledge to get a radiation shielding suit, then drop down the central hole and walk south into a nukage pool. Follow the nukage east and south to enter a room with two spectres, then collect the blue skull key between the two trees by the north wall. Go back to the pit area and head south up some steps to a vine-filled room, kill some shotgun guys then continue east up a second set of steps to get back to the starting area.

Return to the pit room and open the blue door in the north-east corner to get outside, then head south-east through the courtyard to find a vine-covered walkway leading to a small door. Go through the door then head south and east past a couple of imps and zombies to reach a curved staircase, then climb up it to find the red keycard - the key is blocked by a demon (or cacodemon on Hurt Me Plenty skill level or higher), and a closet containing more monsters will open behind you. Go back down the steps and head west to a red door, open it then go straight forward over another walkway to some steps. Go down the steps and look left to kill three demons, then head to the south end of the room - the wall ahead will lower to reveal one or two more demons guarding the exit door, and one to three imps will be released behind you. Go through the exit door and walk straight forward to the exit button.
