Map of Recycling Plant
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Go straight forward to a junction with an imp and shotgun guy, then take the north-west path and follow it until you reach a large T-junction. Take the north path to enter a room with a large round nukage pit, then go through the doorway on the east side to find a couple of monsters guarding a switch. Flip the switch, then go back to the T-junction and pass through the now-open south door to face a few zombiemen. Continue south past a round column, then go up some stairs to find the yellow keycard.

Return to the round room and go up the western staircase, then open the yellow door at the top and kill some approaching monsters. Head north, west then south, following the gray floor, to another staircase, then go up it followed by a second staircase straight ahead that leads to the blue keycard - there are two demons waiting to ambush you as you take the key, and some imps will be released near the bottom of the stairs. Go back to the yellow door and pass through it again, then head south until you get to a blue door and go through it. Immediately look east to kill a shotgun guy then go down the steps next to it to find a spectre guarding a switch. Flip the switch then go back to the previous room, where a thin bridge leading to the red keycard has risen from the nukage; on Hurt Me Plenty skill level or higher, watch out for an ambush by imps that appear behind the key.

Return to the round room and go through the north doorway to reach a junction, then go east to a staircase and climb it before heading south down another set of steps to a red door. Open this door to find a shotgun guy guarding a second door, then go through that door and head round the corner to see another shotgun guy protecting a staircase. Climb the stairs to the exit door and open it to find the switch that goes to E5M4: Phobos Garrison.

Secret exit[edit]

Follow the directions in secrets #3, #4, #5 and #6 below to find the secret exit to E5M9: Wayward Outpost.

Other points of interest[edit]


  1. Head south from the center of the map and east. Head to the right of the stairs to spot a partial invisibility. (sector 177)
  2. In the red key area, drop into the nukage on the east side and follow the trail of armor bonuses as it goes around and to the north. Press on the dark green wall at the north end for a teleporter leading to a rocket launcher and rockets. (sector 171) These items do not appear on Hey Not Too Rough or lower.
  3. At the south end before the steps to the yellow key, get on the middle column on the east side and look east. Shoot the switch to open a wall to the north, then enter and head south for the secret with the megaarmor and a lever switch. (sector 228)
  4. Flip the lever switch in the previous secret and head back to the north end, taking the steps going east and going through the opening to the north to reach the outer courtyard. (sector 49) The courtyard holds various items, including a partial invisibility, a chaingun and a supercharge.
  5. In the courtyard above, head to the west end and a large wall will lower. Enter the star-shaped teleporter to reach the central nukage vat with a computer area map. (sector 180)
  6. A switch is behind where you teleport in the previous secret. Flip it, then go back to the southern end of the map where the yellow key was to reach a courtyard where the secret exit is. (sector 259)
