Do I need to kill all three Secret Keepers and then do the time-limited steps at the green beam on each of my characters individually? Or will the Dual Destiny mission be available for all my characters once I’m unlocked it on one? Edit: I did it! Thanks for letting me know, saves me accidentally doing the whole thing again on my Titan only to realise I already have it. Only (“only” :P) need to get the mission itself done now.
