Hax!Just FYI, easiest way to do this is to go to the 'Respawning Restricted' area and then back out into the game world. Find another area where part of the story missions take place and the enemies will be at L28 also. You can rack up your kills on these enemies and the bonus is if they kill you you don't go back to orbit.
I got a nice little loop going on earth and got my 200 kills in about 45 minutes.
I have the Light beware fusion (solar) maxed out is it really worth the grind to actually do this bounty?
Actually you can go to any area in the Nightfall as long as they are level 28. The current night fall you can go to the back part of the divide and there are five level 28 and the past between the dive and the steppes has level 28. I did a run this morning and cleared 200 quite quick while also been able to do the public events and collects chests.I tried killing the low level hive & fallen that keep spawning in the first area but they don't count as nightfall enemies even though they are in nightfall. They only count when you get to an area with the 'no respawn' symbol. Killed 17 and then got killed. I have legendary fusion rifles in all 3 elements now anyway so not sure if I need pocket infinity. I'll maybe just let it come naturally through doing nightfall each week
Thinking about it, this week's nf should be good for the pocket infinity bounty. The room with the door dinkle bot is opening has heaps of thralls in the first wave. Kill them, let the Knights kill you, rinse and repeat.
