Secrets

 * 1) Use the wall south of the red key to reveal a lift leading up to a soul sphere and a stimpack. (sector 289)
 * 2) At the southeastern part of the level are some rising and lowering square lifts, which will eventually take you to the blue key. On the ledge where the first lift lowers, ride it up, and head to the third lift. From there, make sure the lift reaches the top, then run into the nukage fall. From then on, you can reach the secret exit, but only if you had obtained the red and yellow keys first. (sector 389)
 * 3) In the nukage just south of the large room with teleporting enemies leading to the red key, enter the northwestern nukage fall to find a secret area. To reach the megasphere here, you will have to carefully jump on lowering platforms until you reach the lift. (sector 449)
 * 4) North of the bridge past the three-key doors, near the nukage are some rocks with stimpacks leading to an armor. If you run towards the nukage fall from the armor you will wind up in a cave with a radiation suit and numerous health and armor bonuses. (sector 643)
 * 5) To get the computer area map near the red key, there is a shootable switch in its sector, which opens the door to it. (sector 761)
