In my experience it works best if you plan these things out. I'm putting a group together to knock out all of these DLC achievements Monday December 10th at 8:30 CST
Please have a mic and extra controllers if possible so we don't have to rely on too many people. Just repost the list below and when it fills up that will be the group we'll go with.

4. LV 223
5. LV 223 (guest)
6. LV 223 (guest)
8. Wahoo35 (guest)
If you get on the list just shoot me a FR on XBL.
Looking forward to knocking these out.
