Half-Life: Opposing Force Hints
How do I turn off the gamma ray that is shooting across the hallway?
1 of 7: The button in front of the gamma ray shield does not work. It will just malfunction and cause some explosions.
2 of 7: Read the signs around you. They warn against getting near the rays and so on.
3 of 7: However, one sign at the far end of the hallway, on the other side of the ray, says to turn off the power before attempting maintenance on the gamma ray contraption.
4 of 7: That sign is in a convenient spot.
5 of 7: Right next to the sign is a small metal control box.
6 of 7: Take aim at the control box and fire some rounds into it to kill the power to the gamma ray.
