The Boomsday Project is Hearthstone's Next Expansion

The second Hearthstone expansion for Year of the Raven has been announced and five new cards have been revealed.

  • The expansion launches on August 7!
  • New Keyword: Magnetic - Played by themselves or can attach to a Mech minion to add on their health, attack, and ability.
  • Projects are new spell cards with extremely powerful effects, but they help both players.
  • Omega Project - These cards are normal, but have a Battlecry that works when you have 10 Mana Crystals.
  • There will be legendary spells, such as one that draws your entire deck!
  • We're getting a new Warlock Hero - MECHA JARAXXUS!
  • Warriors are getting a new Dr. Boom as a Legendary playable hero (at least that's what it appears to be in the video).
  • Logging in after the expansion launches gives you 3 card packs and a random legendary minion from the set.
