Other points of interest[edit]


  1. Enter the cave system south of the central part of the map. Make your way to the southwest section where a lone zombieman is and go through the south wall. A cache of stimpacks is in a nearby dead end, and if you head further east, you can find a box of shotgun shells. Behind the moving water walls, you can find shotgun shells and a superhealth. (sector 196)
  2. After raising the bridge east of the central part of the map, head east, then north. Look at the large waterfall at the east side, near the one with boxes of ammo. To get this secret, you need to press on a very small bend of the waterfall near the middle of it, which opens a passage to the northwest. (sector 108)
  3. In the passage that is Secret #2, head all the way through, shooting barrels and small drones in the way, until you come to a room with two switches. Flip the left switch, then return to the large waterfall to find the one near it has lowered. You will find two more boxes of ammo and a backpack. (sector 105)
