The Boomsday Project is a 2018 expansion for Blizzard Entertainment's digital collectible card game Hearthstone, available on PC, Mac, iOS, and Android. Set in the Netherstorm, it centers on the return of Dr. Boom to his secret laboratory, where the villainous scientist and his colleagues have been developing an array of unusual new cards. The expansion introduces mechanical amalgamations, strange crystals, and lab-grown creatures into the game's strategic deck-building ecosystem. Players incorporate these new cards into their decks and compete in the game's standard turn-based card game format, using the expanded roster of inventions and monstrosities to build synergies and outmaneuver opponents. The expansion emphasizes a science and mad-inventor aesthetic throughout its card designs, broadening the strategic options available to players across the game's existing classes.
