Scavenge the equipment of Dead enemies by interacting with them to refill your Supply meter.

Seems pretty cool, i hope when it says "interact with enemies" its not like a CoD deal where it just means run over their corpse. I really hope it means you actually have to go over and push a button to like search through their kit or something kinda similar to having to hold a button to plant a bomb.
