A megawad replacement for Doom. Quite old but theres lots of scary castle levels. Quite an elusive wad.
Map 1 is fairly straightforward. Just find the exit.
Map 2 is rather small. No biggy.
Map 3 requires you to kill the big spider, walk over where it has been
and then back downstairs.
Map 4 wants you to walk over the body of at least one of the two hell barons.
Map 5 has a very obscure solution. Might be best to skip it
(idclev06). I don't want to change it because it remained one of my
favourite maps.
Map 6 is brutal but easy. Just try again and again.
Map 7 is also brutal but more difficult. You need to run through the
back chamber of the castle and then survive long enough for the
elevator to come down all the way in that room. I recommend surviving
in the entrance hall.
Map 8 features the first Heng (a difficult-to-beat Cyberdemon). After
you unlocked him, stay in the centre of the room you fight him in!
Map 9 starts you off against a familiar-looking castle. This time the
exit is not hidden but difficult to reach.
Map 10 required you to find keys all over the place.
Map 11 is rather conventional.
Map 12 is an escape from a prison.
Map 13 continues the escape.
Map 14 is a starport. Find a star ship you can use.
Map 15 is a starship. Find the shuttle to fly away from it.
Map 16 is a space station. Here you'll find the second Heng. Find the
elevator that leads you to the space station's surface.
Map 17 is still the space station. Find the exit to the surface.
Map 18 is the space station surface. Find your way out and back in.
Map 19 is a Cyberdemon trap. Good luck!
Map 20 is the surface of the enemy planet. Find the entrance to the main base.
Map 21 is a castle that hides the main base.
Map 22 is the back entrance to the main base.
Map 23 is a prison escape in the main base. I think it the best level
in the collection (and possibly the only one where I can legitimately
claim that it really is good).
Map 24 is the first real episode set in the main base. Beware the long
elevators.
Map 25 continues in the same area.
Map 26 is the main building of the main base. You'll have to find the
way to the command centre.
Maps 27 to 30 are the command centre. In each you will fight a Heng.
I believe the final enemy is a Spider Mastermind.
Have fun!
