Cataclismo, the acclaimed real-time castle-building and defence game, is getting a paid DLC called The Old Kingdom that adds a hex-based strategy boardgame layer on top of its existing block-building combat. Players will expand their domain across multiple citadels on a turn-based overworld map, similar to the Total War series' split between strategic and tactical play, while still engaging in the real-time siege defence that made the base game stand out.

In the new mode, players manage supply lines and reinforcements between fortresses, research technology, and build up defences to repel escalating attacks from monstrous forces known as the Mist. Publisher Hooded Horse describes it as reclaiming a lost kingdom by growing the realm's economy and military strength turn by turn. The Old Kingdom expansion launches on PC via Steam, GOG, the Epic Games Store and the Microsoft Store on 20th August.
