Today Sara gave us more information about the remaining civ for the “Tides of Power” DLC: Tonga.
Tonga is an expansionist and diplomatic civ with a starting bias for coast and tropical tiles. They obviously get boni related to coastal tiles and exploration, such as their scout being able to enter directly ocean tiles without taking any damage. For more info please check here.
Firaxis also gave us an update about the reworked naval battle, which you can read here and discuss with us here.
