BREAKING NEWS: BATTLETAG UPDATE – 5/19
As we prepare for the launch of Overwatch next week, we have refreshed the free BattleTag update for all Battle.net accounts! We often see feedback with requests to update your BattleTag, and as we move into a new universe filled with soldiers, scientists, adventurers and oddities it’s important that you have a nickname that represents you!
Like your current moniker? No problem! You will continue to keep and use your existing BattleTag without needing to take any action. Want to change it up? Visit your Account Management Dashboard, and click the Change link under your Account Details to the right of your existing BattleTag! Players on your Battle.net Friends List, Heroes of the Storm, Hearthstone, and Overwatch will see the update soon after the change.
In addition to the above update, requests for an option to update BattleTags more frequently is something we hear often from players. We’re exploring the possibilities, and will be sure to let you know of any updates! Keep an eye on our game sites and forums for announcements.
It won’t be long before the agents of Overwatch are recalled to active duty, and we hope that this update helps you get ready!
