Your Doom walkthrough for Level 42: The Factory. Find the Blue Key, Yellow Key, and Berserk, and navigate the tricky lift room to escape.

Alright, let's tackle Level 42: The Factory in Doom. This one's a bit of a maze, but we'll get through it together. Just stick with me, and you'll be out in no time.

Walkthrough
  1. 1
    As soon as you spawn, hang a right. Keep heading straight until you smack into a wall.
  2. 2
    Turn left at that wall, and you'll see another one ahead. Go straight to it, then turn around. You should spot a staircase. Head on up!
  3. 3
    At the top, you'll face a bunch of Arachnotrons. Take 'em out. Once they're all down, keep going straight. You're looking for a door on the right, but don't go through the very first opening you see – it's the second one on the right. Open that door and head inside.
  4. 4
    Inside this room, move straight ahead and drop down to the floor below. Follow the right-hand wall until you find an opening. Go through it.
  5. 5
    Turn right in here, and you'll see the Blue Key right in front of you. Grab it! After that, there's an Arachnotron waiting above you, so take care of that.
  6. 6
    Now, turn around and head all the way to the far end of this room. At the other end, turn left. You'll see a door. Open it and go through.
  7. 7
    In this next area, you'll find some Lost Souls. Clear them out and grab the Yellow Key. Now, leave this room.
  8. 8
    Back in the previous area, go through the opening right next to you. Here, you'll encounter some Mancubi. Once they're defeated, face the opening you just came from. Follow the left-hand wall until you reach a door.
  9. 9
    Turn right at this door, and you'll see another door directly across from you. Open this one and go through.
  10. 10
    You should see a green Armor right in front of you. Walk up to it, and the floor you're standing on will start to lower. Down here, you'll need to deal with some Shotgun Guys. Grab their Shotguns after you defeat them.
  11. 11
    Now, step into the teleporter in this room. It'll zap you outside.
  12. 12
    Once you're back outside, you'll see some Mancubi ahead of you. Take them down.
  13. 13
    After that, look around for two green torches. Drop down to the floor below them, then head towards those torches. There's a door right between them. Open it and go through.
  14. 14
    Inside, grab the Berserk power-up. Then, head through the Yellow Door you see.
  15. 15
    This next room has lifts that go up and down. Be careful, it's also crawling with Cacodemons! You'll notice that every other lift has a switch on it. You need to hit all these switches on the alternating lifts. Doing so will open up a wall near the Yellow Door you just came through.
  16. 16
    Once all the switches are flipped and you've grabbed any extra ammo, head through the new opening in this room.
  17. 17
    Just follow this hallway to the exit teleporter. Step on it, and you'll be on your way out!
Tips
  • Don't rush through the first few areas; take a moment to get your bearings and clear out enemies methodically.
  • The room with the lifts and switches can be tricky. Prioritize hitting the switches while dodging the Cacodemons. If you fall, you'll likely have to start that section over.
  • Make sure you grab the Blue Key and Yellow Key; you'll need them to progress.
