Jackbandit: Is it going to be possible to trade items in the full game? Only with your enemies. Trade your ammo for their loot. You know the best way to deliver ammo to a Cabal Centurian? You’ll figure it out, and it’s tons of fun. As for swapping irons in the Tower? Nope. We want you to earn ‘em. You should be able to tell a badass story for every sweet jewel in your arsenal. Once you earn them, the various Guardians under your account will be able to trade them, but weapons belong to the players who acquire them through action and bravery. -Bungie
