Other points of interest[edit]


  1. Head east from the starting point, then fall into the damaging liquid below with a radiation suit. Use the switch, then head north and ride the lift to the north. Head west and use the wall in the southwest corner with the face to find a medikit and health bonuses. (sector 133)
  2. Head south from the starting point, staying on the walkways until you reach an enclosed area. Jump east into the damaging sludge when you do, then find the slimefall to the east. Shoot through it until you hear explosions, which will get rid of barrels, then head in to get a berserk pack. (sector 219)
  3. Head all the way south from the starting point until you reach a staircase with health bonuses. Instead of taking this staircase, hop off the metal lift to the west into the liquid and look for a red button. After using it, head back to the starting point and head west to a platform that had a soul sphere. The bars to the south are open. Take them to eventually reach a room that has a BFG9000. (sector 247)
  4. At the eastern end of the map where the exit is, go through the northern slimefall to find a radiation suit and a lift with an energy cell pack. Use the lift to reach a megasphere and ammo clips. (sector 283)
  5. Head south from the starting point to the first intersection, then head west into the room. Get to the nearest window, then very carefully inch northeast, onto a thin ledge. This is incredibly difficult to do without falling off, but if you make it, head east to an alcove that has armor bonuses. (sector 319)
  6. Head south from the starting point, staying on the walkways until you reach an enclosed area. Enter, then head west, then notice a switch to the south in the liquid. Flip it to lower the lift to the west, but instead of taking that one, run east and south to another lift that lowered, containing a plasma gun. (sector 333)
