Half-Life: Opposing Force Hints
How do I get out of the initial tunnel system?
1 of 5: The initial tunnel system has a small room off to one side with a bullchicken in it.
2 of 5: There are some alien spores on the wall, too.
3 of 5: If you look up, you will see a sort of shaft that the alien spores have inhabited.
4 of 5: You can use your barnacle to latch onto the spores and drag yourself up, into that shaft, and onto the ducts overtop of the tunnels.
5 of 5: Keep using your barnacle until you can reach a ladder that leads up to the surface.
