What started as a stock Nerf Vulcan—more than enough foam killage for most of us—was modified with four wheels, a turret, webcam and laser sight. And then, as you see in this clip, the tank turned on humans, hunting modders' girlfriends everywhere as if the violence were some sort of game.

In order to accomplish this feat, the guys from Manapotions increased the voltage to the firing motor using 2 x 9.6v battery packs. More juice equals a faster spinning motor. A faster spinning motor means that toy darts will come down on your enemies like rain. As an added bonus, they equipped the gun with a sweet LED round counter and a slick paint job. Seriously folks, this thing is like the A-bomb of office warfare. And the best part is that it is a cheap upgrade. Hit the link for complete instructions on how to do it yourself. [Manapotions]
