"you guys are idiots"-Your Average Troll
The meter you see here near the top of the screen is the health meter you need to get health packs for those cause they don't regenerate, Now the the health your talking 'bout is the stamina, it goes red around the screen (like in Cod) if:
A: you fall your gonna lose all of your stamina and some of your health
B: when you get shot you will lose some stamina, but continuously you can lose all of your stamina and get your health down.
Your thinking that the stamina acts like a shield, that's true it regenerates like a shield. But when your health goes down you need to get health packs. Oh, your welcome.
