As you may know, once in a while a freshly slaughtered combine soldier drops a grenade-like canister that Gordon can use to restore some health. What do you think Gordon does with it? Does he drink it like a can of coke? Spray the green goo inside the canister all over his wounds?) Or is there an attachment for that sort of thing in the HEV? What about poor combine soldiers? Do they gulp it down through their facemasks? Anyways, it would be cool to know what the concept behind it was.
