Secrets

 * 1) Head northeast into the lava from the platforms over it in the starting area, all the way northeast and west to a megasphere surrounded by health and armor bonuses. You will need to get a radiation suit prior to getting this secret if you wish to survive it. (sector 2009)
 * 2) Go across the platforms to the building at the start, but head just east of it and north into a small cave. At the end, open the west wall for a light amplification visor. (sector 2030)
 * 3) Enter the nukage at the north end when you enter the building, then get the radiation suit and go to the southwest wall. Flip the switch and take the lift up. At the top, open the door to get a blur artifact. (sector 2069)
 * 4) Head northeast from the yellow door to lower two walls with chaingunners. You can see a backpack above the east wall. Go there and lower the wall where it is to get to a monster closet with boxes of rockets. (sector 1756)
 * 5) Open the yellow door and head south to the cyberdemon. Use the northwest switch, then head north to find a revenant, energy cells, and a BFG9000. (sector 1781)
 * 6) Get the blue key, then head back south and southeast to the hall. Open the blue door to the supply room, then go to the megaarmor to the north and find the hidden button, which opens two compartments with light amplification visors. Both compartments count as the same secret. (sector 1762)
