Blizzard recently announced that the closed beta of Diablo 3: Reaper of Souls is underway. The development team is reminding everyone who’s hoping to get into the closed beta to opt in via the account management page on the official battle.net site here.
Since the Reaper of Souls Closed Beta test will be featuring all content (with the exclusion of the final boss fight), invitations will be extremely limited. Around the same time as the Reaper of Souls Closed Beta, Blizzard will be launching the Public Test Region (PTR) for Patch 2.0.1! They promised to reveal more information on how to access Public Test Region when it launches.
