Secrets[]
At the start of the level, jump over the posts to either side of the railing behind you. Go to the north of the nukage lake to find a cavern with a teleporter. Use it to be taken to a room containing a supercharge (which you will grab once you move) and a rocket launcher. (sector 6)
While inside the first hallway, press the flat side of the UAC sign. This will cause the table in the opposite room to lower, allowing you to obtain two stimpacks, a chaingun, and two boxes of bullets. (sector 52)
In the same room as secret #2, push the front of the silver computer at the west, and it will sink into the floor. Behind it are a stimpack, armor, a box of shells, and two boxes of rockets. (sector 76)
