It's large 1995 map. Starting area is looking nice, but later author lost creativity and made mazy corridors. Very challenging because of overuse of chaingunners. It's extremely annoying. Lots of traps, Some clever, some not fair.
For 95' map is really ok. A bit "blocky" design, but not bad. Map is rather big, it takes me 40min but i get lost in one place. Some good traps, IMO kinda challanging at the begining, before you get ssg. Overall good classic wad.
Fun map that captures a nice TNT-ish feel with plenty of weird yet also nice looking rooms, groups of hitscanners and demons to blast through, and a sense of adventure to it. Taking the MAP14 slot, you would see the episode 2 skybox of TNT: Evilution and listen to the track "Cold Subtleness", both creating a nice atmosphere to the map. Worth checking out!
Doesn't like the layout and monster replacements, I didn't found RL until got the yellow key and found a lot of rockets, the location where RL is confusing me, and it also not fun when you get kicked down from the cliffs by Revenants, Mancubus and Archviles after the way to Blue key door, the way to the teleporter just far enough to kill you if not killed by monsters which kicked you down. Final timed puzzle room just nasty as the cyberdemon and archvile fights in the same place, not sure why make the level so big but can't make the fights with them also on bigger place too?
It's not bad level but I'm sure the frustration level is sky high, and not sure the slopes from ZDooM do anything good to this level too.
