Lead the last survivors in the aftermath of the Cataclismo as a corrupted world seeks to destroy all that remains of humanity. Build fortresses brick by brick, designing intricate, towering structures of wood and stone to fend off waves of Horrors as they attempt to overwhelm your band of survivors. Command powerful units in their stalwart defense, coordinating their varied capabilities as you race from breach to breach. Lead forays into the unknown to secure the vital resources needed to grow your military might and construction capabilities as you hold fast against the ever-growing onslaught – siege after siege, night after night.
What is happening now
Cataclismo is a real-time castle-building strategy game that arrived on PC in March 2025. The game has now received its first major expansion, The Old Kingdom, which introduces a substantial shift in gameplay direction. Rather than building on the original castle-defense formula, the DLC transforms the experience into a hex-based boardgame where players expand across a map from citadel to citadel. This expansion mode emphasizes supply line management and technology progression alongside tactical defense against enemy forces, effectively layering turn-based strategy mechanics onto the foundation of the base game.
