MAP28: Top Hell (Hell Revealed)

MAP28: Top Hell, designed by Haggay Niv, is the twenty-eighth map of Hell Revealed.

Description
According to the Hell Revealed info pack:


 * This is an underground city filled with all the strong enemies. You will not find weaklings - they simply didn't survive. Also, look for the Cyberdemons' revenge: remember doom2 level 8 (Tricks and Traps)? Now's the Cyberdemons' time for payback!


 * This level is so hard because Haggay got angry after 29 turned out too easy :-)


 * Size: medium
 * Difficulty: very hard

Secrets

 * 1) In the eastern section leading to the yellow door there is a demon-face on the northern wall. Press it to lower an elevator to a secret compartment containing a BFG 9000 and a Bulk cell.
