Half-Life: Opposing Force Hints

Where do I go in the watery room with the broken walkway?

  • 1 of 9: The walkway that you encounter has been damaged.
  • 2 of 9: Not only has part of the catwalk been destroyed, but the glass casing of the big ichthyosaur tank to the left has a large hole in it (look underwater to find the hole).
  • 3 of 9: You will want to kill the ichthyosaurs before you go swimming in their cage. You can do this any way you want.
  • 4 of 9: But did you know that C4 detpacks float? They are very useful in this situation.
  • 5 of 9: Toss one through the crack and watch it slowly rise through the water. When one or both of the ichthyosaurs are near it, trigger the detpack. It may take two or three detpacks to deal with them.
  • 6 of 9: Or you could just stand safely on the broken walkway and shoot your new shockroach at where you know the hole in the glass is whenever the ichthyosaurs swim near it. Fun and easy!
  • 7 of 9: Once the ichthyosaurs are out of your way, start looking for an underwater exit.
  • 8 of 9: There is a grate at the top of the ichthyosaur tank that you can break through.
  • 9 of 9: Do so and swim up the duct behind it to enter the BioDome Drainage System.
