Nothing smashes through Xen invaders like a big ‘ol RPG launcher! There’s something inherently satisfying about pulling the trigger on the Half-Life RPG, aided by cool sound effects and an awesome animation. It’s also fantastic at taking down helicopters, which is exactly what you do after finding the weapon in Half-Life.
The RPG provides explosive power without sacrificing accuracy, thanks to the laser-guidance system. You can still fire the RPG without any assistance, which can be effective in some situations. However, it’s often far more entertaining to guide the rocket around using the laser, taking out enemies that are cowering behind cover.
