At first, you might laugh at this kid, but you've got to hand it to him - he makes all of the weapons from Halo*, they all look dead on (Out of cardboard no less!), and he's even got the moves down. He knows how a Spartan looks reloading every weapon.

Call him silly if you must, but this dude's pretty crafty. I especially like his Machine Gun turret. At the end of the video, he makes a special request for his YouTube viewers...
