Secrets

 * 1) North of the first teleporter is an armor. Note that if you enter the trench south of the teleporter and teleport, you will be unable to access this secret. (sector 110)
 * 2) Obtaining the plasma rifle at the eastern end of the long corridor lowers several sections of wall along the corridor. The westernmost one has a switch which opens up a door in the next alcove along, leading to some enemies, some energy cells, and a switch. There is also a BFG9000 in multiplayer. (sector 68)
 * 3) The switch in #2 opens up a door in the western alcove north of the corridor, leading to a spectre (hard skill only), a box of shotgun shells, a box of bullets, a chainsaw, a baron of Hell (both only on hard skill), a berserk, a soul sphere, and a megaarmor. (sector 189)
 * 4) Approaching the items mentioned in #3 opens up a path to the west from the aforementioned box of shotgun shells and box of bullets, leading (via a door which can be opened manually or using the switch in #2) to a BFG9000, three energy cell packs, two soul spheres, and a megaarmor. (sector 197)
 * 5) Approaching the switch which raises the nukage surrounding the exit lowers several nearby platforms, some of which can also be reached by lowering the lift in the south of this area and jumping. One of these platforms contains a rocket launcher, two boxes of rockets, a megaarmor, and an energy cell (not on easy skill). (sector 150)
 * 6) Another platform contains an exploding barrel and a soul sphere. (sector 149)
 * 7) Another platform contains a chainsaw and four clips (all present on hard skill only). (sector 151)
 * 8) Another platform contains an exploding barrel and a BFG9000. (sector 153)
 * 9) Another platform contains an exploding barrel. (sector 152)
 * 10) Another platform is a long platform which contains two armors and two soul spheres. (sector 44)
 * 11) From the exit, head east, then south down the stairs, then up the eastern of the two lifts. At the top is a blue door leading to a radiation shielding suit, a baron of Hell, four soul spheres, and an alternative exit. (sector 144)
