It seems as though it's one thing after another. Life influence games and games influence life. YouTube user MichaelCiuffo has created a real life FPS styled ammo counter.
The ammo counter keeps track of the shots you fire pretty accurately. Now whether or not that provides a distinct advantage in a real life battle situation probably hasn't been confirmed quite yet, but after being featured on Kotaku, user Michael Ciuffo has announced that he will definitely begin going into production. It might seriously become a cool add-on for those of us that like to go paint balling. Let's cross our fingers that we won't need real guns to appreciate this Life Upgrade.
