Civilization VI will expand further on July 23 with the Ethiopia Pack, which is available as part of the New Frontier Pass or can be purchased separately for $5. This pack will introduce Ethiopia as a civilization, along with new buildings and a new district. It will also introduce a new mode, as long as you own the Rise and Fall or Gathering Storm expansions.

The new mode is called Secret Societies, and it--as you might expect--adds some secret societies to the game world. Discovering one of these societies will unlock a unique, extra-powerful Governor, whose bonuses do not need to be assigned to a specific city.

Once a society is uncovered, the player who found it becomes a member of that society for the rest of the game, and if you form an alliance with a player who is also a member your Alliance Points will accumulate faster, and you'll have better diplomacy options. Conversely, players in other societies are going to be your enemies.
