Other points of interest
Note that for this level, the normal safeguards of telefragging by monsters is disabled, as per standard for MAP30 of any WADs of Doom II based games. Therefore, if this level is played on Nightmare! difficulty or with the -respawn parameter set, respawning monsters may telefrag the player. This also applies if the player happens to be in God Mode or obtains the invulnerability power up.
Basically this map can be finished with just a pistol, note that it is an extremely difficult route. Oh, and DO NOT shoot at all until you get the yellow key.
At the start just go down and press the switch on the left and lower the door which will show a cyberdemon, just go around and go straight up the stairs ahead, avoid the cyberdemon on top and jump off, go straight into the small building, press the switch right next to the megasphere, go outside avoid the revenants, go up the stairs that look exactly like the ones at the start, except this time, jump off the ledge and go where all the mancubus are, and go into the small building again using the mancubus route, get the barons in one side, or they will block you, get the key, dont jump off, just turn around, go to the room behind the stairway (not the start), follow the stairs, avoid the hell knights and the archvile, go straight and open the yellow door, press the switch, get back out, and while the yellow pillar is lowering just keep running into it, once you are able to climb it, go straight up and climb the blue and red and fall down to see the romero head, just go around it and pistol kill it. And you're done.
