For weeks, Bungie has been advertising that the ‘Niobe Labs’ was going to be unlocked today. Niobe Labs is the last bit of official content in the Black Armory dlc ( second to last if you include the Last Word Exotic quest ). Up until today, no one was exactly sure what the ‘Niobe labs’ was, would if be a mission, a dungeon, a Strike, etc. Turns out, it a location, with a puzzle that requires a full fireteam of players all equipped with various forge weapons, you have to look through the scope of a specific weapon to see an invisible symbol which has to be shot in a particular order, and a bunch of other crap ( the community, well the Streamers are still trying to figure it out, everyone else has just lost the will to give a shit ). The first players to solve the puzzle will unlock the 4th and final Forge ( yes, another -blam!-ing Forge ) for the rest of the community.
