Hearthstone: The Boomsday Project Guide
UPDATED 16th August - Our overhauled guide now highlights meta-busting decks for every hero!
The Boomsday Project came as something of a surprise when the first details started popping up in July. Ahead of the first announcement, a YouTube video went live a little earlier than expected and so we learned that Hearthstone's next card set would be based around the lab experiments of the dastardly Dr. Boom.
Since the expansion itself was launched back on the 7th August, we've been busy updating and creating a huge roster of deck guides that will help you get ahead of the competition on the ladder. After the quick expansion overview just below, you'll find our pick of the very best decks to play in the new meta.
Beneath that you'll find details of all the new cards that have been added to the game with the release of Boomsday. Enjoy!
Expansion Overview
First up, here's a quick outline of the headline stuff you need to know about:
- Release Date: The expansion will be released on August 7th 2018.
- Legendary Spells: Legendary Spells are being added to the game for the first time in Hearthstone's history.
- New Keyword: A new keyword called Magnetic is being added to the game. You can play these cards as normal, or fuse them with an active Mech to combine their stats (Think of the Hunter's Death Knight hero power in this sense.
- Pre-order:There are two pre-purchase options. The Regular Bundle contains 50 card packs, the expansion card back and a random Golden Legendary card. The Mega Bundle will contain the same as the Regular Bundle but also include 30 more packs and the Mecha-Jaraxxus Warlock hero.
- Single Player:More single player content is coming! The Puzzle Lab will see players attempting to solve a number of challenges split across four different categories. Our Puzzle Lab Guide has the full lowdown.
