Outpost 21

Outpost 21 (OPOST21.WAD) is a single-level PWAD designed by Scott Amspoker. It was noted by Doomers of that time for its varied environments, its balanced light levels, and its careful matching of monster population to architecture.

The map was originally released May 10, 1994. It appeared on Maximum Doom as OPOST21.WAD (twice), OPOST212.WAD, and MAP04 of NEWLEV2.WAD.

Secrets

 * 1) In the dark area in the south-east is an octagonal pool of water.  To the south-east of this is a darker pool of water, at the north of which is a chainsaw. (sector 45)
 * 2) Before going through the first blue door encountered, take either of the doors on your left and drop down.  At the north is a door leading to a stimpack and a shotgun.  Behind the shotgun is a secret door leading to a passage with a spectre that leads to a room with several health bonuses (the room is also accessible by going through the blue doors). (sector 221)
 * 3) North of the blue key is a room with three switches, all of which open doors leading to small rooms.  The northern of these rooms has a secret door on its east wall, leading to a chaingun. (sector 257)

Bugs
The blue key can be picked up without lowering the pedestal.
