In Hidden Leaders, each player takes on the role of 1 of 6 secret leaders. Every leader is allied with 2 of the 4 factions/colors: The Hill Tribes, the Imperial Army, the Water People, and the Undead. By playing heroes into your tableau, either openly or secretly, you influence the outcome of the conflict.
During the game, the players play hero cards to influence the power of the Hill Tribes (green marker) and the Imperial Army (red marker).
After a certain number of heroes have been played, the game ends. The position of the 2 markers results in a victory for 1 of the 4 factions.
