Secrets

 * 1) At the room north of the start, press on the wall with pipes on it to find a green armor. (sector 850)
 * 2) At the southeast end of the map, find a red button and push it, lowering a wall to the northwest containing a backpack. (sector 869)
 * 3) In the big room at the south end of the map, once you reach the switch on the east side (north of Secret #2), the walls in the big room open up revealing cacodemons. Make sure to flip the switch here to raise the steps, then climb them to the next door, but before reaching the door, jump to the alcove to the left to another switch. Flip this one, then drop back down and climb the steps again. Now jump to the east alcove and through the open passage. Here you will find a megaarmor (not on Hey, Not Too Rough or lower), a box of shotgun shells, a box of ammo, and a medikit. (sector 882)
 * 4) After picking up the yellow key, go back to the room to the east and head for the southwest corner (or head back to the starting room and through the southeast passage). In this passage of health and armor bonuses, when you reach the window, a switch will appear to the south. Shoot it to lower a lift behind you with a rocket launcher and four rockets. These items will not appear on Hey, Not Too Rough or lower. (sector 833)
 * 5) West of the red key, go south to the switch, which opens up the monster closet behind you. In this area, there is a green button on the left terminal. Push it to open a nearby wall so you can get a soul sphere. (sector 835)
 * 6) Go north from the red key room and up the stairs. Shoot the barrel in front of the wall here and open it to find a medikit, energy cells, and a plasma gun. (sector 890)
 * 7) Drop into the nukage where the exit door is and head southwest to the opening where you can find a chainsaw. (sector 663)
 * 8) Grab a radiation suit and head into the nukage where the exit door is. Go all the way around and use the lift to go up. Now press on the wall to the right to find stimpacks, ammo, partial invisibility, and a backpack. (sector 936)
 * 9) After flipping the switch to raise the bridge to the exit door, open the door to the west, heading back to the room just east of where the yellow key was. Climb the steps and collect the computer area map here. This computer area map does not appear on Hey, Not Too Rough or lower. (sector 910)
