Heroes of the Storm officially released June 2nd, 2015, making this year the game’s one-year anniversary. To celebrate such an occasion, as Blizzard does, players will be given gifts for playing.
From June 2nd to the 14th, all players that play will receive a 50% experience bonus while playing. This bonus will also stack with the 50% experience bonus while playing with a friend. Logging in during any of those days, players will receive a special portrait for the anniversary.
As well, a bundle containing The Butcher, Sgt. Hammer, Xul, Lt. Morales, Uther, Kerrigan, Artanis, and Arthas along with Tyrael’s charger mount has been announced. However, a price hasn’t been revealed for this bundle yet.
Just like with World of Warcraft, Blizzard might have more up its sleeve for the popular MOBA’s first year celebrations, although anything past this is purely speculation.
