Other points of interest[edit]


  1. In the cave with the armor bonuses, head east to the bloody wall and open it to find a berserk pack. (sector 17)
  2. As you head north on the west side of the map, you will spot a blur artifact. To get it, when you reach the water, open the south wall. (sector 126)
  3. At the start, before dropping down, examine the east wall. This will cause something lower at the normal exit. When you finally get to the normal exit, flip the side switch to access the next secret. (sector 123)
  4. Flip the switch in Secret #3 and head back north through the new opening to get a medikit and the secret exit. (sector 117)
