Diablo 3 have caused a lot of tension from waiting. Diablo 3 is finally offering beta testing similar to the Starcraft 2 one. You will receive an email with the beta code to sign up for it. You will only receive one, if you opt in for beta testing on your Battle.Net account. If you didn’t receive an invitation code for D3 Beta, you can generate your very own with our Diablo 3 Keygen. There is no limit to how many codes you can generate. Currently, this is a generator that creates Diablo 3 cd keys to be used on your Battle.Net account.
