Your colleagues will reconsider the office as one of the safest place to be once you get your mits on the Mini Weapons of Mass Destruction 2 ($11). Thanks to John Austin, they’ll be constantly watching their backs knowing that you’ve amassed small-scale arsenals fashioned from goodies looted from the supply closet. So next time someone doesn’t return your stapler, refill the printer with paper or take your favorite chicken sammich from the break-room fridge, you’re free to unleash hell.
