Still looking for several online MP achievements for this - will join any group (preferably USA) but I've had some luck with overseas groups too. Need the level 50, Employee, and a few others. Thanks!
Currently looking for Online Boosting help with:
Mortal Kombat vs. DC, SSFIV, BF:BC1, AC:Brotherhood
(if you see a game in my played list, I can probably still help you with it)
