Some maps are fun, others have some weird switch combinations to put pressure in the player, I didn't have a good time with these maps. Just read vdgg review.

Similar to his Iron Halls, square rooms, no keys, interior bloody sewer, few floor height variations. Good gameplay. Quake-y sounds.

A pretty good map semi-slaughter map that uses the Ancient Aliens textures and monsters, is a voyage into some purple/cyan place where you have to climb a fireblu cake after solving a simplicity-like puzzle (cool, i'm one of the 10 people that remember of "Simplicity", do you remember when 13/15 years ago that megawad was the stunning trend in mapping?), overall is a fun map, even if doesn't have too much ammo for beating all the resistance, at least for me.

Linear indoor action, no keys, some quake sounds, cool play if you don't care about boring textures. Totally opposite to his later style -> Gigantic-exteriors.

Pretty cool map for the 1994 standards, good layout and gameplay, even with the high number of monsters (128 on HMP), the level is pretty straightforward but pretty fun.
