Regrettably, this one comes without much context, though there's little reason to believe it isn't genuine. Reddit poster shamguy posted an image he took of an unspecified tunnel in the game, which contains a number of black jars which looks suspiciously similar to the vials from Ridley Scott's Prometheus. In the movie, these vials contained the mysterious, black alien fluid believed to be a bio-chemical weapon built by the Engineers in order to destroy humanity. Though Bungie are most likely just having some fun with a recent pop-culture phenomenon, isn't it cool to think about that black goo seeping out into the world of Destiny?
