Hello Hogardians! The Old Kingdom DLC for Cataclismo is now available, with a 10% launch discount! This is Cataclismo's first DLC, and we're so excited to share it with you. In The Old Kingdom, you'll venture north to reclaim a lost continent in a new strategic game mode. Defend multiple citadels, expand your realm, and build both your economic and military might turn by turn. This time around, nightfall isn't the only reason you have to race against the clock; with each passing day, the horrors will also grow stronger and the next deadly wave will draw closer.

Check out the trailer here:

Here's a quick rundown of what you can expect from the new game mode in The Old Kingdom DLC:

A Grander Campaign: Plan your conquest and manage your realm at the War Table. Spend might to recruit new troops, explore special tiles with unique boons, trade resources for fresh reinforcements, and spend knowledge points to unlock new technologies, abilities, units, and buildings.
Strategic Supply Lines: Marshal resources between your citadels to hold your gains and press your advance. Develop each conquered settlement over time to add to the prosperity of your realm. But plan your routes carefully, because convoys and units travel only a few tiles per turn.
Escalating Threats: Each citadel you take becomes another front to defend, with its own countdown to the next deadly wave. You'll be forced to race troops and resources between them as the assaults mount, holding the line long enough to conquer them all, but beware: the final reckoning has yet to wake.

Wrest the Old Kingdom from the grip of the Mist and rebuild a world where humanity can finally thrive.
