Ahoy: Rivals & Renegades includes the hulking Blackfish Brigade and the sprightly Shellfire Rebellion. It also introduces a rowdy Team mode! In team mode, you can play with the new factions along with the Bluefin Squadron and Mollusk Union from the core game. Sharks and orcas face off against mollusks and turtles! This is an expansion. A copy of Ahoy, the board game, is required to play.
