Secrets

 * 1) Use the blue key to open the nearby wall to the next area. On the other side, look northeast, a bit left from the spinal column, to spot an eye switch in a small hole. Shoot it to open a teleporter to the east. This teleporter takes you to the southeast area where you can get a BFG9000. (sector 81)
 * 2) In the yellow key area, there is a hidden switch at the southwest end. Use it, then go to the northwest part of the room to find energy cell packs and a megaarmor. (sector 166)
 * 3) Head west from where the blue key is to spot a switch hidden in the wall. Use it, then head a bit north from where the blue key is, then all the way west to reach a teleporter, a rocket launcher, and rockets. The teleporter takes you to a soul sphere and energy cells. (sector 170)
