Half-Life: Opposing Force Hints
How do I cut the electricity that blocks my way past the downed Osprey?
1 of 15: You need to locate the source of the electricity.
2 of 15: The source of the electrified fence's power is not apparent anywhere near the downed helicopter, so begin looking elsewhere.
3 of 15: A tunnel opposite the helicopter has one of its doors partially open. It is possible for you to fit through.
4 of 15: Run into the tunnel, deal with whatever headcrabs you find, and run out the other side.
5 of 15: NOTE: You can jump-crouch into the hole in the wall that the headcrabs came out of to find an armor battery.
6 of 15: Some malfunctioning electrical generator hubs seem to be the problem. The question is, how do you turn them off?
7 of 15: The gate leading into the area with the electrical hubs is electrified, as a careless security guard finds out. You need to find another way in.
8 of 15: A nearby vent has been blown off, allowing you entrance into the air duct.
9 of 15: Follow the air duct along until you come to a fan. Another air duct is on the other side of the fan, but you will first have to deal with the electrical currents shooting off of the fan's axle.
10 of 15: Once past the fan, follow the duct along until you come to the vent at the end. Break through and step out into the electrical generator area.
11 of 15: Be careful not to touch anything. The fence is electrified and so are the electrical hubs.
12 of 15: Move around the hubs until you see a sign that says "Generator Controls" with a control switch nearby.
13 of 15: Pull the switch to cut the power.
14 of 15: Be sure to grab the Desert Eagle .357 off of the dead security guard.
15 of 15: The gate out of the electrical generator area and anything else that was previously electrified are now passable.
