Diablo III Beta FAQ
What are your goals for this beta?
The primary reason for the Diablo III beta test is for us to test out our new hardware, see how the server–client infrastructure holds up, and look for bugs in the installer and patcher as well as the game. We’re also looking to get some quality feedback about the beginning game experience and how the different classes feel. The beta test will help us ensure that the release is stable and fun, and that we’re ultimately able to deliver the experience we intend with Diablo III.
How do I sign up for the Diablo III beta test?
To sign up for the Diablo III beta test or future Blizzard Entertainment beta tests, you first need to create a Battle.net account. You can then opt-in to the beta test for Diablo III, as well as beta tests for future Blizzard Entertainment games, through the beta opt-in process. To get started, simply click Beta Profile Settings in Battle.net Account Management. Please note that opting in to a beta test through this method does not guarantee that you will be selected.
If I opted in to the Diablo III beta, how will I know if I’ve been selected to participate?
If you are selected, you will receive an email from Blizzard instructing you to log in to your Battle.net account at
http://www.battle.net if you don’t already have one. You’ll then be able to download the beta client directly from within Battle.net Account Management. We plan on inviting players in waves, so if you do not receive an invitation in the beginning of the testing period, there’s a chance you might receive one in a later wave.
1,000 Diablo III beta keys were promised at BlizzCon; how do I know if I am a winner?
We will be sending out emails with beta keys to winners along with detailed instructions on how to access the beta test. Players who receive a beta key via email will need to create a Battle.net account, click “Add or Upgrade a Game” in Account Management, and enter the key there. The beta client will then be available for download from within Battle.net Account Management.
How long will the beta test last?
We have not determined an exact date for the end of the beta test. We will notify participants when the beta test is nearing completion.
How many players do you plan to invite to the beta test?
The number of players we invite will be based on our testing needs. If during the course of testing we determine we need more players to participate, we’ll invite more.
How are beta test participants selected from the opt-in pool?
Beta testers are chosen according to their system specs and other factors, including luck. Our goal is to have a good variety of system types to best test compatibility.
Which regions will be able to participate in the beta test?
All regions will be able to participate in the Diablo III beta test; however, to keep the process as efficient as possible, and ultimately to release the game as soon as possible, we plan to roll out the beta hardware in waves, starting with North America. This means that players outside of North America who are granted access to the beta test may experience some latency issues. Once the new hardware setup has been optimized, we plan to roll it out in additional regions. This should provide a solid connection experience for beta testers in those regions who are connecting to the new local hardware infrastructure.
What game content will be available in the beta?
You’ll be able to try out all 5 character classes and experience the early stages of Diablo III from the start of the game through the Skeleton King encounter. You’ll be able to interact with new and returning characters in New Tristram and fight the reawakened evils emanating from the cursed Tristram Cathedral. You’ll also experience the randomized elements of Diablo III as well many of the new system designs that take many of the core Diablo design elements to a whole new level.
Will the progress I make during the beta test carry over when the game launches?
No, the purpose of the beta test is to ensure that the game and hardware infrastructure are ready to go as soon as possible. The main benefit of participating is being able to be among the first to play the game extensively prior to release. However, everyone will start on equal footing once the game is launched.
Will the Diablo III Auction House be available in the beta?
Yes, we plan on testing the functionality of the Diablo III gold-based auction house during the beta phase.
Will Mac users be able to participate in the beta?
Yes, Mac users will be able to participate in the beta at the same time as Windows-based users
