Complete Doom Level 57: The Marshes walkthrough, including Cyberdemon boss fight tips and locations for the Super Shotgun and BFG.

Walkthrough
  1. 1
    Upon starting the level, collect the two Shotguns and Boxes of Shotgun Shells in the initial room.
  2. 2
    Activate the switch in the starting room; the exit door will not open until the Cyberdemon is defeated.
  3. 3
    A lowered wall reveals the outdoor area; use your Automap (a map displayed on your Heads-Up Display) for navigation.
  4. 4
    Turn right towards the wooded area containing the Super Shotgun, Armor, Light Amplification Goggles, and a Backpack.
  5. 5
    After collecting these items, the Cyberdemon will appear. You can fight it immediately or gather more supplies.
  6. 6
    Return to the starting building. With your back to the outdoor opening, proceed straight until you reach a ledge.
  7. 7
    Turn left and ascend a staircase leading to a building.
  8. 8
    At the top of the stairs, collect the Chaingun and Box of Bullets.
  9. 9
    Proceed left to find and activate a switch. This switch creates a staircase to a higher platform across from your current building.
  10. 10
    Before heading to the new staircase, jump across the gap to your right.
  11. 11
    Collect the Plasma Gun and activate the switch in front of you. This lowers a lift on the building ahead.
  12. 12
    Ride the lift to the top of the building and collect the Boxes of Rockets and the Rocket Launcher.
  13. 13
    Locate the staircase created by the earlier switch and ascend to the higher platform.
  14. 14
    Follow the ledge on this higher platform to an opening containing the BFG.
  15. 15
    With sufficient weaponry, engage the Cyberdemon. Use all available ammo, including Bullets, Shotgun Shells, Rockets, and Cells.
  16. 16
    Once the Cyberdemon is defeated, the exit door in the level's starting room will open.
  17. 17
    Navigate back to the starting room, enter the now-open exit door, and activate the exit switch to the right.
Tips
  • Use trees in the wooded areas for cover (press the cover button to crouch behind walls or objects) against the Cyberdemon's rockets.
  • Seek protection inside buildings, especially higher ones.
  • When fighting on open ground, strafe to dodge rockets or use building walls for cover.
  • Allow other enemies in the level to engage the Cyberdemon to weaken it.
