Secrets

 * 1) In the maze in the south-west there is a switch which opens a door ultimately leading to a small outdoor area. This switch also opens up a switch in the centre of the maze which lowers a nearby floor, revealing 16 shotgun shells and a megaarmor. (sector 177)
 * 2) The path leading to the blue door has a secret door on its west side (marked with a different texture) leading to six health bonuses, a super shotgun, and an armor. (sector 110)
 * 3) Before opening the blue door, press either of the gargoyles on the south-east wall. They open, revealing a path containing a heavy weapon dude (two on hard skill, a demon (not on easy skill), a box of bullets, a stimpack, and a switch. Pressing this switch opens up a path across a bridge back to normal territory, and also opens up a switch by the stimpack which provides another way of lowering the floors by the red key. (sector 175)
 * 4) Near the yellow key are two sets of bars. Open the yellow ones, then approach the other ones. Doing so lowers a lift just past the yellow bars, leading to two health bonuses and an energy cell. There is also a secret door here, leading to a room overlooking the yellow key area with a box of shotgun shells. (sector 109)
 * 5) Jumping across the gap north of the exit from the west side opens a door in the alcove to the south-east (by the switch that lowers the yellow key) leading to 8 shotgun shells, a demon, and a switch. The switch lowers a wall, revealing a BFG9000. (sector 184)
