replica Uncharted gun," that we posted about yesterday, Sony has told Gamesindustry.biz that it is not officially endorsed and they certainly don't condone it. The gun is supposed to be a replica of Drake's weapon from the 2007 gem, Uncharted: Drake's Fortune. Without official licensing from Sony, however, selling it as such is just a sneaky attempt at cashing in on the game's success.
Sony has said that they are "investigating the source of this product and will proceed with the most appropriate action." Appropriate action, in this case, probably means letting loose their pack of half-starved, feral lawyers. So don't expect it to be around for too much longer.
