Following the Cree announcement last week—and the criticism that followed—2K and Firaxis have unveiled the next civ en route to Civilization 6. Led by Golden Age ruler Tamar, Georgia will feature in the geopolitical strategy game's incoming Rise and Fall expansion.
As detailed in the 'First Look' trailer below, Georgia's unique ability is Strength in Unity whereby the player receives an additional bonus when transitioning into a Golden Age. Naturally, this means Georgia is better placed to achieve and, crucially, maintain Golden Ages over rival civs.
Replacing the Renaissance Walls, Georgia's unique building is the Tsikhe—Georgian fortresses situated atop neighbouring hills and rocky cliffs that provide faith. Moreover, the Khevsureti marks the Georgian's unique unit whose melee approach leverages a combat bonus on hill terrain. As such, the Khevsureti ignores all hill movement penalties.
As for Tamar herself, her leader ability is Glory of the World, Kingdom and Faith. It's described thusly:
Tamar can declare a Protectorate War after gaining the Theology Civic. Considering Tamar’s upbringing—and how she was known to inspire her troops before battle, they gain bonus Faith for a limited time after declaring a Protectorate War. In addition, Georgia gains bonuses as they continue to deliver the word of God. An Envoy sent to a city-state of your majority religion counts as two.
More information on Tamar the Great can read via this blog post. Georgia is set to arrive in Civilization 6's Rise and Fall expansion, due February 8, 2018.
