Mr. Prueitt here. Destiny has recently dropped their new Rise of Iron DLC which introduces us to the new SIVA virus threat, along with giving us some insight into the fate of the Iron Lords. A handful of story missions give our guardians some new areas to play around with alongside a new patrol zone, the Plaguelands. Overall the DLC story is extremely short, but there are plenty of exotics to find and grinding to be done to get raid ready. I am not even close to raid-ready myself, but I have seen and heard that this raid has proven easier than the past few but still is extremely fun!
For you hardcore guardians, I’d say pick up this expansion!
