Industrial is a single-level PWAD for Doom II designed for the Doom Legacy source port, created by Kevin Reay (Magikal). It was uploaded to the /idgames archive on May 17, 2002. As with other maps created by Magikal, this map features extremely cryptic progression and challenging gameplay. The map was created in four months (with another month of final edits), and was created with DeePsea v11.3.

Although the map seems to work perfectly well in limit-removing ports for the majority of the map, it is unbeatable without infinite height on at the very end near the exit door.

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.

Secrets

1. After removing the crate at the east side of the first hall, open the wall there to enter the corridor. Open the north wall there and go all the way to the north to an ammo clip. After doing this, return to the previous corridor to find a room to the south open. Inside, open the south wall to get a stimpack. (sector 1954)
2. Go back to the corridor going north and near the south side, open a wall to the west to find the scrolling switch. Use the west wall here to get the chainsaw. (sector 1961)
3. In the square room east of the starting hallway, go to the northwest corner behind the northwest shack and use the north wall to find a marble hall. Use the wall immediately to the north to get a soul sphere. (sector 399)
4. In the library with the star-shaped pit, go east from the southeast tip of the pit and open the bookshelf there. Use the switch, then run north and into an alcove to the east to use a switch there. Run directly west and use the switch, then south of there to find a passage. Immediately use the west wall from the entrance to this passage to find a medikit and a box of ammo. (sector 396)
5. In Secret #4, open the west wall for a box of shotgun shells. (sector 1234)
6. In the hall south of the library with the star-shaped pit, use the southwest wall to find a rocket launcher. (sector 60)
7. Enter the nukage east of Secret #6, but quickly return to the hall and head to the northeast with two radiation suits. Use the north wall in that small room to find a winding path with boxes of rockets, a medikit, and another radiation suit. (sector 127)
8. In the long corridor behind the east nukage pit, go south and the north and south walls will open. Enter the south compartment and open the east wall to get a box of shotgun shells and a medikit. (sector 125)
9. At the south end of the long corridor, crossing the middle causes the west and east walls to open. Enter the east compartment there and open the east wall to get a medikit. (sector 123)
10. At the end of the long corridor are three switches. Use the middle one, then quickly run south, then east in the corridor to go to the middle, opening the west and east walls again. Quickly run into the west, which has an additional wall open (from the middle switch) and into the room before it closes. Step near the southeast side of the room. Once you do this, leave the room and go east in the corridor again, then north, opening the wall to the north. Open another wall to the north and get the radiation suit. (sector 81)
11. Open the north wall in Secret #10 to find boxes of rockets and a medikit. (sector 83)
12. Open the red door in the area with crates, then, before going through, use the west side of the nearest crate behind you. This opens the compartment north of the door with an arch-vile and a box of shotgun shells. (sector 191)
13. In the same room with the crates, go to the northeast corner. Head west and use the east side of the second crate from the right, which has a beige side instead of a gray side. Go back to the red door and open it, then head south to get boxes of ammo and boxes of shotgun shells. (sector 1488)
14. Open the red door and go all the way west, opening the west wall. Open the wall west of there to get a box of ammo. (sector 1499)
15. In the corridor south of the room with the silver inverted cross, open the west wall, touch the column, then try to go back to teleport behind the column. Lower it here to get a box of rockets. (sector 1490)
16. In the room with several pentagrams on the floor, access the outer corridors via the southeast switch. Head for the switch at the west side, then head back to the south side and approach the switch to the southeast. Once you do this, quickly run back west and north to the west side, and where the switch was that unlocked the one back at the south side, the light is on and you can enter the winding corridor to the north. (sector 1231)
17. As soon as you enter Secret #16, open a wall to the west for a box of shotgun shells. (sector 1507)
18. Go all the way up the winding path from Secret #16, going to the southwest window of the large pool area. Go to the dead end to the north and open it to get a box of ammo. (sector 1873)
19. At the bridge over nukage near the center of the map, going east will cause the wall to close. Go to the wall, look north, and shoot the light on the northeast wall. Shoot the light to the northwest as well, then head east, opening the wall to the left of the switch. The alcove nearby has a backpack. (sector 1505)
20. On the tops of the crates in the central area, go to a circular stack of crates near the northeast end which has a hole, then use the switch to raise the holes. Step over the beige part once you are at the top from the north end and an opening to the north will be revealed. Run through this opening. In this room, open the southwest and southeast walls to get a box of rockets and a megasphere, respectively. (sector 2110)
21. See Secret #20. (sector 2111)
22. Open the north wall in the room with the previous two secrets to find a large set of steps. As you climb up, several compartments will open. When you are almost to the north end of the steps, a small wall near the northeast end (to the southwest) will open. Enter here and use the switch to rise up. However, do not go to the next switch you see, as it will just lower to the previous switch. Instead, stand where you used the first switch and press use again to rise up further, finding a box of rockets at the top. (sector 1039)
23. In the large pool area, get on the east ledge and head to the south side. Open a wall to the south to get a BFG9000. To leave, use the slab to the west, shoot the switch behind it, and press the switch behind you to open the way out. (sector 687)
24. Head west from the north end of the large set of steps. The south wall will open with rising and lowering walls. Move a little west from there until a different area to the north opens. When this happens, open a wall opposite of that entrance instead. Press the switch inside to rise, but stay in place and press use again to rise a second time. You will then have to press in that direction a third time to rise to the top, which has an energy cell pack. (sector 1431)
25. Go back to the large staircase and head left again for the north side to open. Enter it this time and open the wall to access a circular hall. Head to the north side and opposite of the metal wall, open the wall on the inner part to get a megasphere. To leave, open that outer metal wall, the wall behind it, and use the switch. (sector 1473)
26. The large staircase culminates in a large field where lines of monsters will attack you. As you head south, you will briefly unlock three alcoves northeast of the last part of the staircase. In order to get to these alcoves, go to about the part where the revenants come in, stay there for a second or so, then run north all the way to the large staircase. Quickly enter the three alcoves before they close to get two soul spheres and a medikit. (sector 1599)
27. See Secret #26. (sector 1601)
28. See Secret #26. (sector 1603)
29. In the large field, the last batch of monsters to attack you is a wave of arachnotrons. Find the evil eye to the west from where those arachnotrons came from, then head directly east to the wall. Move back a little and press use for the floor to lower. Jump down and follow this path to get energy cell packs. (sector 671)
30. Head up the steps to the south of the large field to access the other field with lots of windows. The east wall will open revealing mancubi. Go towards that area, but use the wall with the satyr face just before it. This lowers two columns to the east with a megaarmor and a soul sphere. (sector 850)
31. See Secret #30. (sector 851)
32. Going up the steps from the first field does open the first window in front of you with the chaingunner. Going below this window and pressing use will rise you up to this window. Open the back wall to access the back corridor. Go to the middle and use the gargoyle face to find a hidden room. Use the switch in the back, then head east (carefully to avoid the nukage pool to the side) and into the chaingunner compartment here. Open the north wall to find a secret switch. This is one of two that can unlock an energy cell pack at the east side of the back corridor. (sector 2103)
33. After getting the blue key, head to the north end of the field with the silos, using a recessed wall and a switch to lower a sliver of ground on the nearest cage. Use the wall there to rise up, then open the back wall and head east, going up some steps. Open the southeast wall in this room, then open a wall immediately to the east to find a teleporter. (sector 1761)
34. When you take the teleporter in Secret #33, leave and head to the north steps, which will lead back to Secret #26. At the southeast part of these steps, open the south wall and get the berserk pack. (sector 1834)
35. After getting Secret #34, return to the room where you got Secret #33, where there will be a new alcove to the west. Enter it and use the back wall to get boxes of rockets and boxes of shotgun shells. (sector 1227)
36. From Secret #35, return to the room to the east, then head north and all the way west, then south. This is where you can get the yellow key by using the blood to the south, however the secret sector is the alcove to the east with the arch-vile. (sector 1230)
37. After getting the yellow key, return to the large staircase, heading north from the end, heading to the northwest side where there is a gargoyle face with yellow bars. Open this wall and press the switch to open another large staircase going northwest, but also open the wall northeast of that switch to get nineteen boxes of rockets and an energy cell pack. (sector 2091)
38. Open another wall northeast of Secret #37 for six energy cell packs. (sector 2118)
39. Go through the extended large staircase going to the north end and east, until you see a smaller set of steps along the way. Descend and go up to the wall with the face and it will open, while a block behind you rises and lowers. When that block is lowered, climb up to the east, but quickly return to the room you opened and go to the southeast to get the soul sphere. (sector 2075)
40. Raise the platforms that are at the east end of the extended staircase, then follow them to enter the cage with the mancubi at the south end. Open the back wall to get energy cell packs and a medikit. (sector 2082)
41. Take the teleporter in the cage with Secret #40 to get to the north cage. Open the north wall here to get more energy cell packs and another medikit. (sector 2080)
42. This last secret sector is unobtainable as it is one of the monster closets in the level. (sector 1659)
