Other points of interest[edit]


  1. On the ledge where you are supposed to jump to the blue key, look southwest for a shootable switch. Shoot it, then go back to the ledge that you jumped from before (this ledge is accessed from the red key door, and the lift east of the nukage, in the northern part of the map). The new opening at the end of this ledge leads to a berserk pack. (sector 94)
  2. At the northeastern end of the map with the glowing floor, look at the northeast corner of the block here to see that one section of it is purely brown in color. Use this part of the block to open a passage to the south, which winds its way to a soul sphere. (sector 98)
  3. In the nukage at the northern end of the map, go to the far southern end of the nukage to spot an opening where you can find a computer area map. (sector 260)
  4. In the open room near the mini-maze at the southern part of the map, you can find a blinking square. Step on it, then run north through the corridor, and when you see an opening on the inward bend, take it. This is a lowered lift, which will take you to a blur artifact. (sector 264)
  5. To reach the invulnerability near the starting point, run into the big nukage pit where the three switches are, then run as far northwest as you can. A radiation suit in a corner is in front of a section of the wall that looks different than the rest. Press on this section to reveal a nearby passage, which has a lift that takes you to the invulnerability. (sector 267)
