Half-Life: Opposing Force Hints
Where do I find the switch to the crossing barrier blocking the tram tracks?
1 of 6: Look just above the crossing barrier. There is a small control room that probably has the switch to it.
2 of 6: However, getting there won't be easy. There are quite a few Black Ops assassins running around. You will have to take them out before you even have a chance of riding the rails.
3 of 6: If you have a squad, bring it with you. You will probably lose whatever guys you have with you, but they will definitely help you out in the long run.
4 of 6: Be sure to grab their ammo and/or weapons after they're dead (especially the cool M-249 SAW machine gun that one of them has).
5 of 6: Once the assassins have been killed, find the staircase leading up to the control room. Pull the lever to move the cross barrier.
6 of 6: Hop onto the tram car and back it up to where you can flip the switch (shoot the arrow symbol with the handgun) and proceed down the tram tunnels on it.
