We're inviting you to join us for the midnight launch of Diablo III! In addition to local retail shops' midnight launches, we're holding a number of demonically charged worldwide launch events in major cities where you can join Blizzard to celebrate the release of Diablo III and pick up your copy of the game. Each event will have its own activities, giveaways, and contests, so see the press release for further details and be sure to check the launch event site for more info on the one nearest you.
Diablo III Midnight Launch Events
Whether you're attending a launch event, grabbing the game at a local store, or waiting patiently at home for your digital version to unlock, you'll want to be ready to jump in right when the servers open.
For the Americas region, comprising the U.S., Canada, Latin America, Australia, New Zealand, and South East Asia, the game servers will go live at 12:01 a.m. PDT on May 15. As a reminder to our Latin American players, the digital version of Diablo III will go live on May 15, and the retail version will launch on June 7.
For the European region, the game servers will go live at 00:01 CEST on May 15. As a reminder to our Russian players, the Russian-language version of the game will be available digitally and at retail starting June 7.
Don't forget to create your BattleTag -- it's important to do so now if you haven't already, as it's REQUIRED TO PLAY DIABLO III. Also note that if you'd like to receive a digital copy of Diablo III free, there are still a few days left to sign up for the World of Warcraft Annual Pass.
We hope to see you at one of our Diablo III launch events, and we look forward to seeing you in-game on May 15!
