Description
According to the Hell Revealed info pack:


 * One of my first maps for Hell Revealed and still I like it a lot. This is a large underground base, and the first real challenge in Hell Revealed. If you can't stand Ultra-Violence - this is the time to switch to a lower skill level. The last level in the first episode of Hell Revealed has no mercy (3 cyberdemons, 2 spiderdemons, 16 archviles and a lot more).


 * Size: large
 * Difficulty: hard
