After a not-so-subtle teaser trailer from Blizzard and a series of leaks, the official word on the new Hearthstone expansion is here, courtesy of BlizzCon. Hearthstone: Forged in the Barrens will take us, naturally, to the Barrens, a Horde-heavy area in WoW and general Warcraft lore. The new expansion is due to launch this year - the Year of the Gryphon, in Hearthstone terms - alongside some major revamps to basic Hearthstone play.
The new keyword this time around is Frenzy, which activates whenever a minion takes damage and survives, to dish out effects like dealing damage to all enemy minions. We're also getting new types of spell cards that will upgrade over the course of the game, gaining more power as you reach five and ten mana.
This expansion will also introduce a new mode called Hearthstone Mercenaries, an RPG-style affair where you build a team of Warcraft heroes, take them through a randomly-generated series of levels, gaining levels and new equipment as you go.Best Hearthstone decks, The best card games on PC, Free card games
