Technically the first map sets in real life university, or at least the first officially accepted as one of those kind of maps. The map Is pretty complex and some areas are neat for a map made in 1994, big open structures with some good simple details in It, the layout Is intricate and good, expect for a pair of dead rooms hunting for keys and other goodies, but it's a good way to tell the player to explore the place. The only big issue is the yellow key door in the main courtyard area that doesn't open (at least in Woof port, the "latest" release) for some weird reason. Good stuff btw.
I feel like I increasingly come across these Eternal levels where there are wide open spaces that would normally feel desolate and empty, but something about the inclusion of these odd little setpieces makes it feel... oddly touching. It's like he isn't playing by the same rule book as other people. The castle map in this WAD is like being shrunk down and getting to walk around a diorama that someone has built.
Practically a Single player campaign sets in a very dark maze of corridors and ventilation tunnels (reminded me of Aliens TC), conceptually is not a bad map but in reality the broken and cryptic progression made me dislike this, as well as the blocked exit room by a impassible line. Too large for DM too imo. Wasted occasion for something decent.
