E4M9: Thy Mappeth Faileth (Thy Flesh turned into a draft-excluder)

E4M9: Thy Mappeth Faileth is the ninth and secret map of Thy Flesh turned into a draft-excluder. It was designed by Matt Powell (cannonball) and uses the music track "Oberon Iron Mine," from .

Essentials
Take the shotgun, rocket launcher and other items in front of you then drop down the hole ahead - you will fall into a damaging blood pool and will see some zombies and demons ahead, along with a cyberdemon on a tall platform. Step on to the marble step on your left to get out of the cyberdemon's line of fire and kill all the surrounding enemies, then follow the blood east, north and west past more enemies until you get to some steps leading up to a walkway. Follow the walkway round, using the red columns as cover where necessary, until you reach the south-east corner where you will find the red skull key along with a chaingun and a radiation shielding suit.

Drop down to the blood and go to its east side to find a red key door, open it and go up some steps to the cyberdemon's platform. As you reach the top of the steps the back wall will lower to reveal an outdoor area with imps, lost souls and cacodemons, and some demons will teleport to the platform - a wall on the east side of the map will also lower and reveal more cacodemons. Take the plasma gun near the center column and use it to clear the smaller enemies, get the cyberdemon and cacodemons to kill each other through infighting, then go to the outdoor area on the west side and climb up the south-west steps to reach the yellow skull key.

Drop back into the blood and go to its south-west corner, open the yellow key door here and walk round to a skull switch that will raise some steps leading up to where you found the red key. Go up these steps and continue east through another yellow key door, then turn right and right again to find the blue skull key - equip the plasma gun before approaching it, as demons will be released behind you (as well as one or two barons on Hurt Me Plenty skill level or higher) and one of them will teleport to you and cut off your escape. With the blue key, go back to the cyberdemon's platform and head up the north steps to an exit door. Open it and turn left to see the white exit teleporter in front of you.

Other points of interest
Climb up the rocks on the north side of the yellow key area for a berserk pack.
