Hearthstone: The Boomsday Project (2018)

Can you feel it? That electric tension on the wind, the reek of ozone and Khorium, the distant rumble of explosions; there’s science in the air! Word around the inn is that Dr. Boom has returned to his secret laboratory in the Netherstorm. No one knows exactly what the mad genius will unleash, but a lot of very, VERY strange cards have found their way into decks around here lately: mechanical amalgamations, eerie crystals, revolting, lab-grown monstrosities… the good doctor and his esteemed colleagues are working on something big! Time to venture into the Netherstorm, find the lab, and uncover what these maniacs are up to.
