 * 2) Head to the room south of the aforementioned gray corridor and press on the wall where the dead marine is. Inside are health bonuses, a super shotgun, and rockets. (sector 84)
 * 3) In the room south of that room, use the switch to open two closets. Enter the southwest one and use the switch there, then return to Secret #2 and flip the switch you see inside. Return to the room to the south and enter the southeast closet, then go into the alcove with the soul sphere. (sector 91)
 * 4) On the way to the red key, open a wall south of the red door to find a backpack. (sector 124)
 * 5) In the central room with the yellow door at the north end, open the southwest door, take the lift up, use the switch, and enter the corridor to the south. Open the bloody wall at the east end of this corridor to find armor bonuses, a soul sphere, and a passage back. (sector 201)
