DOOM 3 Hints

How do I get through the locked door in Hydrocon Control?

  • 1 of 8: Try its control panel.
  • 2 of 8: It'll say that you need the PDA of either P. Harvey or B. Lipsitz to open the door.
  • 3 of 8: Well, Paul Harvey has left the planet, so you'll have to locate Lipsitz's PDA.
  • 4 of 8: To get to it, go through Hydrocon Control's unlocked door to get to Hydrogen Siphon.
  • 5 of 8: Then climb a utility ladder in a dark corner to get to Hydrocon Stabilization.
  • 6 of 8: NOTE: The utility ladder is unreachable until you get some wall panels to slide aside by walking around near the computer banks. You'll know the panels have opened when an imp attacks you.
  • 7 of 8: In Hydrocon Stabilization, squeeze around behind some large vertical pipes to find the spot where G. Kreitman is, then run past the big up-and-down machine to get to the PDA you're after.
  • 8 of 8: SHORTCUT: After you get the PDA, you can drop down a nearby shaft to get back to Hydrocon Control without having to go back the way you came.
