Detailed walkthrough for Doom II's Map 22, The Catacombs. Find all secrets, items, and defeat enemies with step-by-step instructions and tips.

Walkthrough
  1. 1
    At the start, kill the Chain-Gunners to your right by getting between the pillars. This area is [SECRET 1/3].
  2. 2
    Left of the starting door is [SECRET 2/3], containing a Specter and a SUPERCHARGE. Save this item.
  3. 3
    In the main area, lower the central column to kill a Pinky. Ride the column up to face a large group of enemies: three Chaingunners, two Revenants, more Chaingunners behind bars, and Specters in the acid. Use BFG, Rockets, or Chaingun.
  4. 4
    Drop into the acid, grab the RADIATION SUIT, and clear the area with your Super Shotgun. Consider leaving a second Radiation Suit.
  5. 5
    In the NORTHWEST corner, lower a platform. Kill distant Imps, then find a BUTTON that opens a path to the middle area for a Rocket Launcher and other supplies.
  6. 6
    Return to the button area, note the Specter, and grab the Berserker Pack from a nearby wall. Follow this path, beware of Imps, and enter the Teleporter.
  7. 7
    The Teleporter leads to a ledge where you can grab the BLUE SKULL KEY. An Imp might follow you.
  8. 8
    Return to the middle hub area. Take the NORTHEAST corner downwards. Kill two Pinkies and a Chaingunner.
  9. 9
    Open the Blue Door and hit the SWITCH to pass the bars. Take the right path first. Be cautious of a MONSTER CLOSET opening on the right wall, releasing three Chaingunners. Collect health from their room. A Skull Switch here reopens earlier bars.
  10. 10
    Take the other path, which leads to a drop with Imps. Kill them. A Baron of Hell is behind a door; hit the nearby switch and defeat him.
  11. 11
    In the Baron's room, find two Skull Switches. The left opens the door, the right lowers the ground. Stand on the lowered ground to be raised to the Red Skull Key!
  12. 12
    Find the nearby demon-wall and interact with it to open a path for [SECRET 3/3]. Go through slowly.
  13. 13
    This teleporter returns you to the start area. Collect weapons, including the Plasma Gun, and warp back to the middle hub.
  14. 14
    Head back to the beginning (from the hub, take the SOUTHWEST corner) to retrieve the Supercharge. Return to the hub.
  15. 15
    Take the SOUTHEAST corner from the hub. Kill Chaingunners, grab items, and proceed through the Red Skull Door to fight more Chaingunners.
  16. 16
    The final room contains two more Chaingunners before the exit. Hit the button to finish the map.
Tips
  • Save frequently, especially before the large fight in the central area.
  • The Supercharge is best used for the initial large enemy encounter if you have it.
  • The Radiation Suit is crucial for navigating the acid.
  • Explore all paths to ensure you collect all items and ammo.
  • The Plasma Gun is found after completing Secret 3/3.
