Satan's Lair v1.0 http://www.doomworld.com/idgames/?id=689
an extremely large maze of a level, with all the good weapons and keys hidden behind invisible walls. 350+ monsters.

Satan's Lair v666 http://www.doomworld.com/idgames/?id=1599
the doom2 version, has lots of additions and more invisible secrets. the yellow key actually has a use now. but just surviving the first room is tough. 550+ mo
nsters.

they're fun when you know where everything is and can plan out a route. but getting to that point, well, turn the map cheat on is all i can say, you'll save yourself a lot of tedium.
