Worldbreakers: Advent of the Khanate is a customizable two-player card game. Players start the game with a Worldbreaker that has a unique special ability and a deck of 30 cards. Each player aims to be the first to reach 10 power, which is gained by developing Location cards and by attacking the opponent.

The game is divided into rounds, during each of which the players alternate taking turns. A turn is composed of one action, such as gaining mythium (the currency of the game), drawing a card, playing a card, or attacking the opponent. Worldbreakers has three card types: events, followers, and locations. Events are impactful one-time effects. Followers are people who join your cause and can either defend your board or attack your opponent. Finally, Locations are places where mythium can be collected. They have a numbered list of stages, each of which can be developed for a one-time bonus such as power or resources.

Worldbreakers: The Indigo Sisterhood is the inaugural expansion to Worldbreakers, a tactical two-player card game. You start the game with a Worldbreaker that has a unique special ability and a deck of 30 cards. As the game unfolds, you'll recruit followers to claim the board and develop location cards to accumulate resources and power. The first player to amass 10 power emerges victorious!

The Indigo Sisterhood enhances the gameplay with fresh events, followers, and locations for all four guilds. It also ushers in two new Worldbreakers: Miriam, entrusted by the Moon guild with the mission to locate the Indigo Grotto, and Kublai Khan, a distinguished master of the Stars guild. Additionally, the expansion extends the narrative of the Worldbreakers solo campaign, drawing players deeper into the unfolding saga.
