Today at PAX West 2019, Arenanet announced a giant new block of content that is available free for previous owners of the Path of Fire or Heart of Thorns expansions, The Icebrood Saga. Beginning today, Heart of Thorns is now also free for all Guild Wars 2 players.
One of the major new additions is Strike missions, 10-person boss encounters that tap into the feel of both raids and metagame living world content. New masteries keyed into the flavor and feel of the Spirits of the Wild and Norn deities also flesh out the new offerings.
The new content begins on September 17th, but like many previous living world additions will continue to receive new additions during the extensive course of its run.
