Hearthstone’s Knights of the Frozen Throne expansion is live

Move over, dinosaurs. Death Knights have come to Hearthstone. The digital card game giant’s Knights of the Frozen Throne expansion is now live on PC and mobile.

Knights of the Frozen Throne adds 135 new cards, including the new Death Knights. These replace your Hero character with more powerful variations. The set also focuses on Deathrattle effects and Lifesteal, a new keyword that heals your Hero for damage dealt. The expansion also has a single-player campaign. The prologue and first wing, The Lower Citadel, are open now, and additional bosses will become available during the next two weeks. Beating the prologue nets you a free Death Knight Hero card, so it’ll be worth playing.
