An impressively large and labyrinthine map, even by 2018 standards. It was enjoyable for the most part, with reasonable health and ammo balance, and interesting to explore. My one big complaint is the teleporters - the map would have already been difficult enough to navigate without apparently patternless teleporters all throughout the map!
You can watch my two-part playthrough here:
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.
