Secrets

 * 1) Go through the door to the east of the start room.  To the east is an area blocked by a low wall of varying height.  Pressing the southernmost part of this wall lowers it, allowing access to this area, where there are 16 shotgun shells and a box of bullets. (sector 259)
 * 2) In the south of the level is a long area with four structures.  Take the northernmost of the paths heading east from this area, turn left at the junction, press the switch at the end of this path, double back, head north then east, step on the raised section of floor to lower the wall to the south, head south then east to a door.  Go through this door and head west up some stairs then up a second staircase.  Now walk east along the ledge to reach a soul sphere.  After getting it, drop down, head west, and press the switch to return to the area with the four structures. (sector 193)
 * 3) The northernmost of the four aforementioned structures can be opened by pressing the shiny section of wall on its north-east side.  Inside is a zombieman or 1-2 imps. (sector 2)
 * 4) The south-eastern wall of #3 opens on pressing, revealing a stimpack and eight shotgun shells.  There is also a spectre here on hard skill. (sector 204)
 * 5) Go through the door immediately west of #3.  Pressing the south side of the southern platform in this room lowers the northern platform, on which lies a partial invisibility. (sector 176)
