Hearthstone’s latest expansion, The Boomsday Project, is now out for all to enjoy. Included among the 135 new cards, are legendary spells – 1 for each class.

There’s also a new keyword – magnetic, allowing you to fuse together mechs.

There’s also free stuff, as blizzard puts it: “For a limited time, log in to claim a random Class Legendary minion (or Hero card), and three card packs—both from The Boomsday Project—FREE!“

And then: “Get 3 more The Boomsday Project card packs FREE when you log in after The Puzzle Lab launches starting August 21.“

The Puzzle Lab is a bit of single player content coming a little later. Basically, you use your cards to solve puzzles.

Check out more about the expansion on the official site.
