Hey, so I've killed 3 walkers, Once on the moon in the anchor of light Once on earth in the divide And once in the story mission "The Devil's Lair" None of these have counted for me and I've even attempted to discard the Bounty and pick it back up to see if it makes the difference, I'm pretty annoyed about wasting plenty of my time waiting at these spawn locations for the Public Event to start and pushing my way through the Strike for it all to be completely and utterly fruitless. Pretty Pissed, Local_Brian
