An amazing hellbase style level mixed with a bit of cave exploring, utilizes ZDoom effects to create a nice atmospheric environment to play in. I played on UV and found the difficulty to be fair while still presenting a challenge in a few spots. Overall it's pretty good but could of ended a little better as I am not a fan of arena endings.
I have a soft spot for levels set in somewhat realistic facilities that also feature a light horror theme, however, what I don't like are levels full of what can be surmised as annoying monster encounters. Specifically what I find annoying are the monsters placed on UV which lead to rather poor level flow. This level does look good and has a nice custom song playing but the stock scream sound effects that play somewhat frequently do detract from this. Overall this is an okay level that could very easily be made good if monster flow was made better and the screams were played less often.
I was loving it, had a fair bit of challenge. Every fight really put you to the test. Excellent map design, too. You clearly worked hard on it, and that is not lost on me. That being said, as soon as it hit whispering winds, I instantly hated it. It just devolved into finding one of 20 invincibility power ups, and spamming the bfg. Took all the fun out of it when you're backed into a corner against 100 barons, 100 revenants, 100 cacos, 5 cyberdemons, 600 imps, 250 zombie gunners, a spider mastermind, and 20 arch-viles that revive the fuckers, and all you can do is spray the bfg and hope invincibilty doesn't run out.
