ArenaNet has announced that closed beta testing for Guild Wars 2’s Heart of Thorns expansion will begin on May 26th. It will run in two-hour blocks, and it’s intended to test the stability of GW2’s “new PvE outpost-event content structure.”
Testers can use a revenant or any of the game’s eight professions to play “a small amount of expansion story content” as well as beta outposts and associated adventures on the Verdant Brink map. Time blocks and further details are available on the official Guild Wars 2 website.
