Secrets

 * 1) In the nukage area at the west end of the map, take the west set of steps and go south. Use the switch for the lift, ride it up, and head north to the switch door, which counts as a secret. (sector 125)
 * 2) At the northern hallway, open the wall with the poison sign to find medikits, a fuel tank, and an energy cell pack. (sector 278)
 * 3) At the nukage area at the south end of the map with two pillars, take the steps to the south up, to the west side. Normally you would hop across the pillars to the east, but if you press along the north wall, you will discover a secret teleporter that takes you right there. (sector 303)
 * 4) At the south end of the map, follow the trail of health bonuses east and north. A dropoff and a door are to the east. Enter through the door for a radiation suit, and then use the wall behind it to reach a hidden flame thrower. (sector 335)

Bugs
