I can’t believe it: Crusader Kings 2, one of the coolest games ever, is getting yet another piece of DLC, four years after it was first released. The game’s newest expansion is called The Reaper’s Due and it’s focused on plagues and diseases of the Middle Ages—most notably, of course, the Black Death, which may have killed a third of Europe’s population.

‘Crusader Kings 2: The Reaper’s Due’: What We Can Expect

It’s no surprise that we’re getting a new Crusader Kings 2 DLC. While Crusader Kings 2: Conclave was the last major piece of DLC for the game, lead designer Henrik Fåhraeus told us in an exclusive interview that there would still be smaller pieces of DLC here and there, even while he has moved on to Stellaris. Crusader Kings 2 still has life in it yet! And with The Reaper’s Due, that life takes the form of death.

So far, we don’t know a ton about The Reaper’s Due. It’s clearly one of the smaller DLCs, but the effects on the game could be profound. Here are the official bullet points, via Paradox Development Studio:

• Epidemics Boosted : As diseases may spread from province to province along trade and sea lanes, they lower your manpower and sap your wealth
• Hospitals and Royal Physicians : Prevent the outbreak of disease in your kingdom, and make sure your courtiers have access to the latest in Dark Ages Medical Science
• Prosperity and Royal Focus : Well managed provinces in peaceful kingdoms will pay huge dividends in gold and levies
• Seclusion : Shield yourself from the diseases tearing your kingdom apart, even if it means ignoring the plight of your people
• New Event Chains : Is the new epidemic the End of Days? Is there someone else to blame for these horrors? Are there supernatural origins or solutions to the world’s problems?

The effect these changes will have on Crusader Kings 2 aren’t obvious, but it sounds like they’ll have the desired effect Fåhraeus has alluded to before: Making it harder for the player to blob up endlessly and sweep over the whole world. The Black Death will be a major setback, slowing down consolidation across Europe and beyond. But those new event chains, as usual, will be where a lot of the action is. Hopefully, the arrival of the Black Death will be as momentous an event as the declaration of the First Crusade—an event that will affect the kingdoms of Europe for a century or more to come. That seems like the overall purpose of The Reaper’s Due: Add a little terror and misery to the midgame of Crusader Kings 2, with big effects down the line. We don’t have a release date for Crusader Kings 2: The Reaper’s Due just yet, and that makes sense—none may know the hour of death’s coming.
