World of Warcraft: Shadowlands – Alert Alpha Coming Soon – Game News
There is an indication that the Alpha of the MMO expansion World of Warcraft: Shadowlands could begin shortly. At least Blizzard Entertainment recently added a corresponding version to the Battle.net catalog – but in an encrypted form.
After some time of relative radio silence, something seems to be happening again regarding the MMO expansion World of Warcraft: Shadowlands. As the magazine Wowhead.com reports, among other things, the go-ahead for the alpha test of the add-on could begin shortly. There is a reasonably concrete hint for this.

The developer studio Blizzard Entertainment recently added an alpha version 9.0.1 to the Battle.net catalog. However, this is only available in encrypted form, so that data mining to track down specific details has not been possible until now. That should only be the case when the World of Warcraft: Shadowlands Alpha Test actually starts – whenever that may be. Blizzard usually organizes a "Family & Friends Alpha" for the WoW extensions, in which only friends and family members of the employees are allowed to participate. A closed beta test then usually follows a little later, in which only invited players are allowed to participate.
Registrations for the WoW: Shadowlands beta are currently not possible because Blizzard Entertainment has changed the system. In the past, you could express your interest in a beta in the account settings, which is currently not (any longer) possible. However, there are many indications that the next big step will soon take place before the official release of the add-on and that a lot of new information will be released to the public. We will keep you up to date!
