Welcome to Half-Life Answers. What would you like to know?

Mostly they are like a secondary health; the function that armor serves in older FPS's. In original half-life it also runs the Flashlight; though in HL2 there is a separate "Aux. Power" for that. Some things, like radiation and explosion damage use less power than they would health. While on others the amounts are roughly equal.
