Other points of interest[edit]


  1. North of the starting point, just before the tan flesh stairs leading down, go onto the platform and press the hidden switch to lower a lift to a megaarmor. (sector 191)
  2. West of the blue door, walk through the bloodfall to find a switch, raising the platforms leading to Secret #3 and Secret #4. (sector 361)
  3. Once you have the red key, use the switch in Secret #2 and go up the platforms. Open the furthest red bars to collect energy cells and a BFG9000. (sector 363)
  4. Once you have the red key, use the switch in Secret #2 and go up the platforms. Open the closest red bar to collect a megasphere. (sector 372)
  5. In the blue key area, an arch-vile will attack from a broken cage here. Enter the cage and walk through the bloodfall for a partial invisibility. (sector 492)
  6. In the metal room accessible from the bridges, use the lift to reach a megasphere and a rocket launcher. Now, jump towards the column directly south and while falling, shoot the wall with a rocket to bounce underneath the floor you were on previously. You can then collect the red key. (sector 702)
  7. Once you get the red key, go to the room behind where the spider mastermind was and open the red bars. Fall in here to collect an invulnerability and fight a cyberdemon. (sector 800)
  8. In the rocky red area at the northeast end of the map, go towards the medikits to spot a hard-to-see switch. Use it then run northeast and down the lift, where you will spot an arch-vile and a switch. This switch crushes the arch-vile as well as the hidden ones in the hallway with the bridge. (sector 926)
