Age of Zalmoxis is an ancient fantasy open-world grounded in history. The game focuses on the Eastern European Kingdom of Dacia. It begins shortly after their ruler, First King Burebista, is assassinated. As the Kingdom shatters into tribes, Dacian nobles compete for leadership. Celtic, Roman, and Sarmatian armies prepare to invade and supernatural threats appear. The Great Wolf Zalmoxis sees this and sends heroic souls down to the Realm of Earth. Players take the role of a proud Dacian champion, whose body merges with a heroic soul. They will fight otherworldly monsters and mortal foes who seek to further fragment the Dacian Kingdom.
