That's the thing. We're not boosting a specific game, we're boosting whatever the group requires. For example, if I were to require the online achievements in Stranglehold, I'd make a post in the group. If someone else needed them, then we'd boost. Essentially it's a multi-purpose trading thread, except all the members are reliable (at least until proven otherwise in some cases).
You can join if you like, you don't have to boost anything you don't wish to, and you don't have to offer help to anyone if you don't wish to. It's all down to the individual.
I'm not much of a booster, mainly because I work a ton, so it's hard for me to keep to any kind of schedule. Also, I can be called to work at any time, so I always feel like a douche when I have to bail. hahaha I appreciate the invite though.
Do you boost? If so, please feel free to join my boosting social group, I'm always on the look out for x360a members that have half a brain cell between their ears... One of the more important aspects of boosting in my opinion. The others being dependability and maturity.
Anyway, if you want to join, there's a place for you.
