i am trying to get the “all alone” achievement for reach, but i do not know what playlist to matchmake in. i have never seen a defiant map in living dead, but i do not want to go on a wild goose chase in squad dlc, and same goes for the “bounty hunter” achievement. help a brotha out?
Bounty Hunter you can do in Anniversary FFA since Headhunter is in that variant.
All Alone HAS to be done in Living Dead but it appears that NO ONE that frequents that playlist on a regular basis has bought the DLC so your best bet is to find a large group and full party boost it. 
Find 11 others that have the Defiant map pack and start running through games quickly until Condemned/Uplink comes up. To boost the odds of a Defiant map showing up vs a Noble or Anniversary if everyone has the same DLC, delete Noble and Anniversary from your HD and re download them after you get your achievement.
Good luck!
alright, thanks man, ill give it a try, sad part is that few of my friends play reach anymore, and the ones that do don’t have the maps. still though, i suppose i just need a few friends and a few extra controllers, although i am already banned for doing that in an earlier attempt, i can’t get double-banned or anything like that? banception?
Please do not idle controller boost, that is definitely bannable.
There are a lot of people looking for those achievements still, you could try setting up a hunting party here. 
i have the defiant map pack and also want this achievement,
add me as a friend, my GT is the same as my username here.

alright, i will not do it again, though i did know what i was getting into, i have learned my lesson, because the only thing i got out of it last time was a credit ban, and being told off by a monitor is more than enough to do it.
