My friends and I are pretty excited about what's coming in the Dialbo III expansion pack, Reaper of Souls. There's been a friends and family beta of the expansion pack going on, but now some of the public can get in on the action.
The closed beta is going on right now and you can get into the fray. There's going to be a very limited amount of people let in though, but if you want to try to get in, just set that you are interested in beta tests on your account page and your name will be thrown into the hat. It's that simple.
You'll be able to copy your existing character over to the beta servers, but don't expect the reverse to happen. Oh, no auction houses will be accessible in the beta as well.
So, if you want to try and get your hands on going against Malthael, here's your chance.
