Hearthstone: Announcing The Boomsday Project

This is a major expansion for the core digital strategy card game, requiring the base game to access its content. Released in 2018, it plunges players into Dr. Boom's Netherstorm laboratory, introducing new cards themed around mad science and volatile inventions. The distinctive feature is the introduction of cards with countdown timers that trigger powerful, often randomized, effects after a set number of turns, adding calculated risk to the established strategic framework. It is available on PC, Mac, iOS, and Android.
