Other points of interest[edit]


  1. At the area with nukage in the center of the map, there is a passage behind two barrels that leads to a medikit, a health bonus, and two armor bonuses. (sector 46)
  2. Head east from where the yellow key is to the blue-floored corridors. Head south, then east, then to a switch. After using the switch, run back to find the middle block has lowered with partial invisibility and shotgun shells on it. (sector 104)
  3. At the south end of the map, flip the switch, then jump to the yellow key platform as quickly as you can. From there, head around the wall to the south and take the lift down, then enter the room before it closes to find rockets, a backpack, armor bonuses, and health bonuses guarded by an imp. (sector 106)
  4. At the northernmost area of the map you will see two shotgun guys behind a wall. The platform in front of them holds health bonuses, armor bonuses, ammo clips, a chaingun, and a megaarmor (not on Hey, Not Too Rough or lower). The only way to reach this sector is to have the shotgun guys shoot at you through the window, so that they hit the wall to the right of the window, which will open the wall on that side. (sector 194)
  5. At the nukage pit in the southeast part of the map, fall in and enter the northern corridor. Get on the lift and ride it up, then go to the soul sphere and rockets (the rockets do not appear on Hey, Not Too Rough or lower) for the secret. (sector 172)
  6. Head south from Secret #5 and around the perimeter as quickly as you can, as the west section of the perimeter will be dropping. Get on the platform with the rocket launcher, ammo clip, and shotgun shells. You only have one shot to reach this secret. (sector 136)
