Completing the Pocket Infinity Bounty

Found this on a forum post "When you spawn on the road when you load up the Nightfall, turn around and cross the Forgotten Shore until you get to the hive area beyond it. There will be 2 lvl 30 dregs and then a bunch of hive mobs, and that's how you know you're there. Kill them with a fusion rifle, and then continue on, killing everything in your path. You'll end up underground, and go through the Grottos on your way over to the Sepiks Prime strike area... Everything you kill in there counts for the bounty. Once you come out in the Rocketyard, you can go to orbit and do it again. If you die, you'll respawn right there, and won't have to worry about the Nightfall kicking you to orbit. Solar burn is still in play, so break out the Murmur for easy mode. Juggler is also in play, so carry some Special Ammo synths, or leave the private area and kill a bunch of mobs to get green ammo drops". Basically instead of starting the nightfall mission, turn around and go all the way behind you, past all the ships and follow the rear path around until you see the two dregs. Kill everything in all areas with level 30 enemies and after your run you should have about 60 or so kills. Go to orbit and restart.
