Borderlands 2 - Eridium Blight - Turrets, Comms Dishes, Volcano, Pipewalk, Vault Signs & King Mong

Ok, this is the big one. All the Eridium Blight Challenges in one run. View description for quick links.
It's a long video, but I really believe all the context is worth it. This level is kind of mess - it might take you some time to unlock everything, but if you do the missions from the board, it should pretty much unlock the whole map. Enjoy!
