Other points of interest[edit]


  1. To get the rocket launcher north of the starting point, just head up the steps around it going counter-clockwise and jump to it from the southwest end. (sector 27)
  2. Head to the water north of the start and head east. Follow the health and armor bonuses to a super shotgun. (sector 30)
  3. Use the switch to the east of the red key, which opens several compartments around the whole map. Head back to the entrance of Secret #2 and head northeast, then north into the room containing an ammo clip, a health bonus, an armor bonus, and a berserk pack. (sector 189)
