Half-Life Hints

I can now move around the flooded lab room. What do I do in here?

  • 1 of 8: Before you do anything else, investigate the tall cabinet to the right of the health station. It has an armor battery hiding inside it.
  • 2 of 8: You may notice a vent on one of the walls. It was previously unreachable because of the electrified water situation.
  • 3 of 8: Break through the vent and be prepared for a surprise attack from about three headcrabs. Dispose of them and you can travel through the air duct.
  • 4 of 8: Hop into the air duct and follow it along.
  • 5 of 8: You will come to a room with a fan in it. Stay crouched to avoid being chopped to pieces by it. (Don't worry about the various headcrabs dropping in; the fan will take care of them.)
  • 6 of 8: The air duct will bring you into the area above the ceiling panels.
  • 7 of 8: Run onto the ceiling panels to fall through into a hallway that was previously locked.
  • 8 of 8: You can also unlock the doors that previously barred you from this area and go get your security guard pal from earlier.
