Below you'll find the weapons trailer for Assassin's Creed III—weapons you can use to open the Assassin's Creed III special edition!
I propose you steal a rifle from an unsuspecting family member, spin around and catch your little brother with the bayonette and then use the bloodied tip of the blade to cut open the tape. Too smooth and stealthy? Are you too excited to daintily remove the seal on your AC III?
How about the tomahawk? You could role and chop your special edition behind the knee, but be careful not to cut through the disc. Old fashioned? Just use the hidden blade to stab between the lid and side of the box. Voila!
