Other points of interest[edit]


  1. When the level begins, at the bottom of the stairs, the wall to the west end of the tunnel is made of thinner rock than the rest of the wall. Push it to uncover a berserk. (sector 122)
  2. Out of the four wooden panels on the central structure, one does not bear any skulls. Shoot it to reveal a switch, and then shoot that switch to reveal a supercharge to the north. (sector 222)
