Blizzard made a whoopsie today by accidentally unveiling the new Hearthstone expansion before they intended, but they decided to roll with it anyway.
The Boomsday Project features none other than Dr. Boom and is the first expansion since Goblins & Gnomes to focus on mechs. 135 cards to be added, with a new keyword – Magnetic. These cards will allow you to fuse two cards together.
There’s also a new type of spell, Projects, which have powerful effects, but give the benefit to both players. Each class is also getting a new legendary spell.
Read more about the expansion on the official site, and watch the video below.
