Secrets

 * 1) In the south is a room with four stimpacks containing a switch which opens up access to the next part of the level. En route to this room is a niche in the wall which marks a secret door leading to two imps (not on easy skill), two lost souls (hard skill only), two boxes of shotgun shells, and a berserk. (sector 135)
 * 2) In the north of the level is a room with a switch which opens up the door to the next corridor. In this room is a secret door to the south-west leading to the cage (seen en route) containing two shotgun guys, a baron of Hell, a soul sphere, and a megaarmor. (sector 177)
 * 3) The curved staircase in the east has a secret door en route (marked with a green texture) leading to a room with access to rooms containing a chaingun, a rocket launcher, and a box of rockets. (sector 264)
 * 4) En route to the blue key is a corridor with two short green firesticks. There are two secret doors along this corridor marked with misaligned textures - one, to the west leads to a rocket launcher and a box of rockets. (sector 350)
 * 5) The other door (see #4) to the east leads to a lift to a teleporter. (sector 311)
 * 6) The teleporter in #5 leads to a room with some enemies that will be killed on exploding the barrels, as well as a backpack, a rocket launcher, and a box of rockets. (sector 329)
