Secrets

 * 1) The door behind you at the start opens on pressing to reveal an energy cell pack. (sector 252)
 * 2) The opening room has a secret door (marked with a different texture) on the south wall, leading to a zombieman, a shotgun guy, and a shotgun. (sector 101)
 * 3) The back wall of #2 is a secret door leading to a shotgun, five zombiemen (three on easy skill), 0-3 shotgun guys, a cacodemon (hard skill only), four health bonuses, and a megaarmor. (sector 105)
 * 4) Just as the first staircase starts to curve is an alcove to the west. This has a secret door on the back wall leading to a chainsaw and a demon (two on hard skill). (sector 110)
 * 5) Whilst ascending the second curved flight of stairs, a door will open behind you. This leads to an imp (medium skill only), a spectre (hard skill only), a zombieman, a shotgun guy, two health bonuses, and a backpack. (sector 116)
 * 6) In the north of the level is a series of rising and lowering floors above some nukage. The southern part of the nukage has a secret door between two evil eyes leading to an imp. Shooting the no-entry sign here raises the floor, allowing access to a BFG9000 and an energy cell pack. (sector 126)
 * 7) Part-way along the curved staircase in the north-west is an indentation in the north side. This marks a fake wall, behind which is a teleporter leading to the yellow key area. (sector 135)
 * 8) The room north of the yellow key lift has a secret door to the west, leading to two boxes of bullets, and two boxes of shotgun shells. (sector 97)
 * 9) The back wall of #8 has a secret door leading to a medikit. (sector 99)
 * 10) Walking along the curved staircase leading to the yellow key area opens a door behind you leading to a path that provides an alternative route to this area. (sector 139)
 * 11) After going through the teleporter behind the yellow door, enter the octagonal room and press the switch. The area to the west has a secret door (marked with a Poison sign) leading to two shotgun guys (one on easy skill), a demon, and a switch which opens up a room to the north with a BFG9000. (sector 155)
