Secrets

 * 1) In the yellow key area, look at the six columns before the yellow key room. The backside of the northeast column has a gargoyle face instead of a lion face. Press on it to open two doors, both of which lead to a BFG9000 and some energy cells. (sector 336)
 * 2) Run around the hub area counter-clockwise, and after crossing the northeast corner, quickly run west and look southwest for a skull switch. Shoot it to raise a bridge nearby that leads to a super shotgun. (sector 345)
 * 3) After dealing with the spiral where the red key is, you will come to a room with several revenants on a high wooden ledge and some mancubi on the ground. Get rid of the enemies, then use the small lift opposite of where the wooden ledge is. Grab the invulnerability and ride the lift up. Now shoot a rocket at the wall so you bounce back to the wooden ledge, and the wall behind you will open revealing a partial invisibility and lots of ammo, as well as health and armor bonuses if you go north. (sector 410)
 * 4) When you use the skull switch in the blue key zone to go up one of two lifts, take either one. When you enter the caged room, the two side compartments on both sides containing chaingunners and cacodemons will open. With these compartments open, head out and into the right one, opening the wall in the back to get a backpack. The passage past the backpack leads to shotgun shells, boxes of ammo, medikits, a soul sphere, and a megaarmor. (sector 446)
