  1. Sector 290: In the corridor in the far east of the map, press the northern green panel, as it lowers to allow access to the ledge. A computer area map can be found here.
  2. Sector 592: Near the end of the long lava hallway, right before the room with the switch, an inaccessible room with two radiation suits, a medikit, an energy cell, and several armor bonuses can be seen alongside the hallway. Shoot the switch inside this room to open a hidden door nearby, revealing another switch. Press this switch to open the room with the suits.
  3. Sector 765: In the room south-east of the red key, find the alcove with the chaingunner and the flickering lights. Press the back wall. A platform with a megaarmor lowers.
  4. Sector 828: In the round computer room with a mancubus, jump onto the western ledge. One of the computers can be lowered to reveal a megasphere.
  5. Sector 1098: Next to the exit, turn right and jump from the high platform to the nearby ledge and turn left to find an opening. Inside is a large room with dead bodies, a rocket launcher, and elevators leading up to three soul spheres.
