I joined this beta very recently, and soon after got another code. I figured I would pass it on.
It’s obviously a one-time use code, so if you used it successfully please comment or tell me on Twitter (@jamest1080). If you don’t know what Path of Exile is, I definitely recommend checking out the site and getting a feel for what PoE brings to the “diablo-clone” genre.
EDIT: Key should be used and done now. Have fun!
