The first episode of the 3rd season of the living world will be titled From the shadows, will be released on July 26 and will pick up the story of Heart of Thorns from where it left off.
In order to play the Season 3 episodes, players will need to have Heart of Thorns. You will also need a level 80 character, but purchasing Heart of Thorns will give players an instant level 80 boost so they can jump right into the action. Players will not need to have completed the Heart of Thorns story to unlock and play the new episodes. LEpisodes are unlocked by logging into the game while the current episode is active and will remain permanently unlocked so that players can enjoy them. Players who do not already own Heart of Thorns will be able to “pre-order” an episode by logging in while the episode is active, but will not be able to play until they purchase Heart of Thorns.
Living World Season 3 episodes will be released every 2-3 months. Living World episodes will be accompanied by the kind of content and updates we’ve been adding to our quarterly Season Updates, but the update frequency may be higher. Our goal is to deliver quality content at a sustainable pace to advance the story of Guild Wars 2 and open world gameplay while supporting the other game modes.
You will find more information in the Guild Wars 2 official site
