Weather you harvest the little sisters, or you save them, by the end of the game will you have collected enough adam to upgrade all your weapons completley? What I don't want is being able to upgrade all your weapons completley with the exception that you can't mod your revolver at all simply because there isn't enough Adam in the game to do it. So do you think that the game will supply you with enough Adam or items/parts to successfully upgrade all your weapons completley?
