Other points of interest[edit]


  1. In the southwest part with the lifts leading up to the red key, take all three lifts up, then make a running jump to the ledge to the south that has a chaingunner and an imp. When you make it, the wall will lower revealing rockets, boxes of rockets, an energy cell pack, and a soul sphere. (sector 216)
  2. On the western ledge of the big lava area, jump to the southwest section where a cyberdemon is. Press on the higher wall and quickly enter the teleporter on the right to telefrag the cyberdemon. (sector 274)
  3. In the big lava area, drop to the level with health bonuses and go all the way north into a cave with rockets, boxes of rockets, an energy cell pack, a megaarmor, and a radiation suit. (sector 374)
  4. Make your way to the flesh and rock room at the southeast end of the map. When you enter from the north entrance, you will actually lower a lift. Quickly run south past the eye, dropping in, then west and past the area with candles before it closes, and you will be able to get ammo and a megasphere. (sector 383)
