Secrets

 * 1) Cross the nukage at the start, but look for a corridor leading south. Take that corridor to find a radiation suit and partial invisibility. (sector 53)
 * 2) Pick up the yellow key, then head to the hallways in the center, which now have new compartments with former humans and imps inside them. At the south end of the halls, open the north wall in the left compartment, pick up a box of shotgun shells, and take the lift to find health bonuses. (sector 57)
 * 3) As you approach the blue key, two compartments to the left and right open up. Take the hall past the right compartment and enter the teleporter to get ammo clips, a medikit, and a green armor. (sector 120)
 * 4) As you approach the blue key, two compartments to the left and right open up. Enter the north corridor in the left compartment and go until the next fork, where you can find a switch to the south. Flip it, then go all the way to the southeast part of the map. A new area to the south is open, containing stimpacks and a rocket launcher. (sector 155)
