MAP24: Post Mortem (Hell Revealed)

MAP24: Post Mortem, designed by Yonatan Donner, is the twenty-fourth map of Hell Revealed.

Description
According to the Hell Revealed info pack:


 * The very hardest map in Hell Revealed. This one is a complete murder - only for the very best players. And there are too many things to save the game on Ultra-Violence, so unless you are really good, try a lower skill or the "shortcut way" (get jumped by the archviles [sic] in the BFG area to the final switch and quickly run to the end).


 * This level is an underground structure. That blood is dangerous - watch your radiation suits and don't fall. Mistakes are not forgiven here!


 * A special credit goes to Kai-Uwe Humpert for recording this one, and with a great lmp, too!


 * Size: medium
 * Difficulty: you're dead

Secrets

 * 1) When following the bridge from the starting platform north you will trigger two alcoves with Archviles to open west and east of it. Both alcoves together register as a secret. Straferun in from the bridge and find one Bulk cell in each one.
 * 2) After raising the stairs on the platform with the red-keycard-bars you can straferun from the top of the stairs to the platform north of it and get a Megasphere.
 * 3) From secret #2 you can straferun to the octoganl platform north of it to get 2 Bulk cells.
 * 4) Directly east of secret #3 is a structure with a corridor running in its middle from west to east. Drop down in the blood and enter the teleporter in the middle of that corridor. It will take you to the oval platform in the southeast with the columns. There is a Megasphere, lots of Box of rockets, 2 Bulk cells and a BFG 9000 there.
 * 5) From the stairs of the large building east of the starting face northwest. You will see a structure with a winding corridor leading in. Drop to the blood and find a Invulnerability artifact there.
 * 6) In the very east of the map (in the blood behind the eastern building with the exit) is a Radiation suit and a hole in the ground in front of it. Run into / over that hole to get a Invulnerability artifact.
