About Expansion - Crusader Kings II: Sunset Invasion

Expansion - Crusader Kings II: Sunset Invasion - about the game
In the late 13th century, Europe faces a fresh peril from strange ships along the Atlantic coast, marked by winged serpents and grinning skulls. This strategy expansion introduces a fantasy twist with an early-rising Aztec civilization invading like a plague, driven by bloodthirsty gods. Players defend their realms against this mid-to-late game threat in Crusader Kings II. New portraits, shields, and units depict the Mesoamerican invaders, alongside their unique culture and religion. Provinces risk human sacrifice upon capture, while a transoceanic plague spreads terror. Grand strategy fans who relish schemes, thrones, and survival against overwhelming odds will find this alternate history challenge gripping.

It is the late 13th century and Europe is still reeling from the all-conquering Mongol Hordes. Just as the Lords of the West breathe a sigh of relief, another threat looms on the horizon. Strange ships bearing winged serpents and grinning skulls, symbols never before seen in the known world, have been sighted all along the Atlantic coast. As the sun sets on the shores of Morocco, Portugal and Ireland, the largest fleet that has ever set sail approaches land, ready to invade in the name of blood thirsty gods...


Crusader Kings II: Sunset Invasion is the third DLC expansion for the critically praised strategy/RPG Crusader Kings II. This fantasy scenario marks Paradox Development Studios first departure from history. Hearing of Europe from travelling Northmen, the blood drenched Aztec Civilization has risen early and now spread like a virulent plague. Prepare to defend all you hold dear against the Sunset Invasion!


Crusader Kings II explores one of the defining periods in world history in an experience crafted by Paradox Development Studio, masters of Grand Strategy. Medieval Europe is brought to life in this epic game of knights, schemes, and thrones.
