Half-Life: Opposing Force Hints
Where do I go after the tram ride?
1 of 9: The tram ride is not very long.
2 of 9: You end up at a small abandoned security outpost with a single assassin bunkered just outside of it.
3 of 9: Take out the assassin and begin looking for a way into the security outpost.
4 of 9: Jump-crouch through the nearby broken window, being careful of the nearby live wire.
5 of 9: Grab as much ammo and health as you can. Be sure to break even the smallest boxes as they may contain useful items as well.
6 of 9: Once done, proceed to climb up the fallen pipe onto the ceiling panels.
7 of 9: Push either the barrel or pushable box up next to the pipe on the live wire's side and crouch-jump carefully onto the pipe from on the box or barrel. Climb up the pipe slow and easy to avoid electrical shock damage.
8 of 9: Break through the only vent up in the ceiling and crawl into the air duct.
9 of 9: You will end up just outside the Lambda Core.
