Other points of interest[edit]


  1. After you press the switch where the chaingun is and open the door, go to the right and into the liquid to fetch a berserk pack. (thing 405)
  2. In order to make the hidden blue skull key appear, you will need to destroy every single barrel in the map. They are located throughout and there is a series of them on far away platforms in the eastern quadrant. Once all of them are destroyed, the blue key will appear at the starting point, where the megasphere was. (thing 83)
  3. With the blue key in hand, make your way to the northernmost room and press the blue switch. This will cause the room to descend and you will be ambushed by several imps. Once they're dead, another switch will appear, allowing the room to go back up and the compartment holding the cyan demon key will finally be accessible. (thing 82)
