Half-Life: Opposing Force Hints
How do I reach the mortar launcher?
1 of 10: A few things have to happen first.
2 of 10: There is a military radio nearby. If you can get to it, you might be able to call in some reinforcements.
3 of 10: The radio is in a small room that can be gotten to by walking through a small door just next to one of the garage doors. A single assassin lies in wait.
4 of 10: Once you use the radio, your fellow soldiers will know your position. Unfortunately, so do the Black Ops.
5 of 10: Two or three Black Ops assassins will be waiting when you return outside. Deal with them and then find out where they came from.
6 of 10: The Black Ops assassins opened up a hatch leading down to some pipes. Grab the ammo and begin looking for some sort of path.
7 of 10: The pipes are far apart enough that you can crawl in between them. Use the boxes to maneuver over to the pipes.
8 of 10: Crawl in between the pipes until you come out inside a building.
9 of 10: The building is full of Black Ops assassins, but at the top is the door you've been looking for. It leads out to where the mortar launcher is.
10 of 10: That's the "right" way to do it. You can seriously shortcut that way by using your wondrous barnacle weapon. Run across the field and up one of the two slanty ramp-like things near the big "Ordinance Storage Facility" sign that's near the mortar platform. Run over next to the platform and use the barnacle on the Black Ops guy to pull yourself up there and chew the man up. You can now skip to what's covered in the next question.
