The Witcher 3: Wild Hunt‘s first expansion Hearts of Stone is releasing on the 13th of October 2015. About a month away with a ridiculously low price point. A teaser trailer has been released for it to give an idea of how the expansion’s story will be going, and 3 new screenshots.
The expansion can be played while even if you didn’t finish the main story for the game, but keep in mind that this expansion difficulty level is 30 and up. If you started a NG+ then this expansion will be leveled up with the rest of the game.
