The upcoming expansion for World of Warcraft Battle for Azeroth launches next month and Blizzard has released a new trailer showcasing Sylvanas Windrunner’s Anger. The trailer gives a short insight into the character’s past and her anger. In war, nothing is certain. In just one moment, a single action can determine victory or defeat. For Sylvanas Windrunner, warchief of the Horde, war has led her to many such moments—including one that will change the course of history on Azeroth. Battle for Azeroth launches on August 14th. For those hoping to get into World of Warcraft players will no longer need to purchase the previous expansions.
