The Chaos mod features the unique unit called Chosen, which replaces normal swordsmen.
The mod very much feels like it came right out of its own universe and integrated like an official new civilization. Like other leaders and civilizations, this mod comes with its own unique units and features their own special ability. It adds a new civilization to the game, The Hordes of Chaos from Warhammer, led by Archaon the Everchosen. The Chaos Civilization mod by RSJ-87 is for Civilization V and specifically works when players own the Brave New World and Gods and Kings expansions.
