Finally played this one today, pretty good for an old-school level, hub layout, so not so linear, varied locations (including a huge canyon area and an underground cavern), LOADS of monster traps triggered by linedefs, including traps WITHIN traps (very nice). Not too much of a challenge, but quite fun.
Good atmosphere, but ruined by the terrible gameplay. Tons of identical enemies attacking you over and over, plus some very dark levels where it's impossible to see where you're going, all amount to a mod more annoying than scary.
REally good and well interconnected map in the style of E1 with some hints of E2 and Doom 2 E1, some cool new textures and even some boom effects like a colored deep water pool, highly recommended to give it a play! Is a fun map!
