I saw this on Reddit, Original Post (-->> https://www.reddit.com/r/DestinyTheGame/comments/3m1ue1/just_received_black_spindle_from_daily_heroic/) Basically while you're completing the heroic story you have the opportunity to complete a side quest that, when completed in the allotted time, will drop the exotic version of black hammer (a 310 light level sniper rifle). Things to know: 1. Proceed with the heroic story mission as quickly as possible (there is speculation that there is an unseen timer controlling the side quest availability) 2. When you get to the third room requiring relics to open the door follow the path to the Ketch ship instead 3. If the door is open you will be prompted to kill the Taken on the ship and a timer will start 4. You have 10 minutes to kill ALL the Taken and must kill all in each room before the next door will open. 5. Even if you kill the ultra in the last room, if there are still additional enemies alive when the timer ends you will fail. 6. The ketch is not a darkness zone, and after a timer you can revive yourself If you fail you will be kicked back to orbit and have to start the whole mission over again, but Reddit users are reporting you can attempt the mission multiple times. UPDATE: Bungie developer confirmed that it will only be available when "Lost to Light" is the daily story, but it will be back in rotation another day if you miss it today.
