Promotional Destiny T-shirt anyone? No? How about one fired from a custom merch delivering Gjallarhorn. Yeah, that's more like it. The team at Bungie was glorying in the rather special weapon at E3, sending T-shirts flying at convention goers as they queued to play new expansion The Taken King and even ending the show with Gjallarhorn fireworks. Just don't expect this from Xur anytime soon.
