My brother and I finished the hidden mission in the daily heroic story. He posted the vid (check out Guided Gaming on YouTube) but I'm not on my computer, hence no link yet, will update after I get some rest. First, you'll need to get the first memory fragment in the tunnel under the first chest in the VoG. The second memory fragment is on the way down the alternate path from the Templar room to the Exotic chest on top of a rock. The Third and final one is in the jumping puzzle room. There's a hidden path to the left that goes around and down to a platform with the ghost that will trigger the platforms to spawn and that far portal to activate. Go through the portal to fight a Blighted Descendant which will unlock Praedith's Gift. A chest with a Legendary Engram and Praedith's Ghost, which you can turn in at the FWC Vendor... Sadly, no exotic was found.... :( EDIT: Added video link of the stream, he's making a walkthrough vid as well. :) EDIT 2: Original Stream can be seen here now: https://www.youtube.com/watch?v=4J3lDEVQDFM I added the walkthrough video to the top :) enjoy! EDIT 3: WARNING, If you do this in a fireteam and a member enters the darkness zone before you pick up the first ghost, it WILL NOT COUNT!!!
