Secrets

 * 1) The curved staircase leading to the area surrounding the nukage pit has a secret door on the south-east wall leading to a radiation shielding suit and some health bonuses. (sector 111)
 * 2) Shoot the three exploding barrels to the north-west of the aforementioned nukage pit. A step is revealed, allowing access to the pit. It is possible to walk through the nukage waterfall, leading to a BFG9000 and (on hard skill) a megaarmor. (sector 175)
 * 3) The room east of the nukage has a secret door directly ahead from the door into the room (on the east wall) leading to a megaarmor (or four medikits on hard skill). On easier skills this is marked by armor bonuses on the floor. (sector 127)
 * 4) Directly south of #3 (south-east of the console) is another secret door (on the east wall) leading to a soul sphere (or an armor on hard skill). On easier skills this is marked by health bonuses on the floor. (sector 130)
 * 5) Head north from the initial diamond-shaped room to reach a room with a switch. This switch reveals three teleporters - take the eastern one (on easy and medium skills) or the western one (on hard skill) to take you onto one of the ledges. From the eastern ledge, run north through a fake wall (which has a different texture) to reach a backpack. (sector 224)
 * 6) The northernmost room (with the yellow door) has a pillar in the west which can be lowered by pressing its west side (marked by one or more candles), revealing a plasma rifle. (sector 191)
