Half-Life: Opposing Force Hints
Rocket-Propelled Grenade Launcher (RPG)
The RPG packs a lot of punch. It launches rocket-propelled grenades in one of two modes. The first is a straight-shot (dumb-fire) where the rocket hits the initial target no matter where your view shifts. The second is a laser-guided shot whereby the rocket is guided by a laser that you control until the rocket detonates. Hence, you can guide rockets around corners, up stairwells, and towards moving targets. The RPG carries 1 rocket at a time with 5 max. It can be used underwater.
