This is an action-adventure game in which players control small Lego figures modeled after characters from the Pirates of the Caribbean franchise. As players traverse castles, pirate ships, and tropical environments, they swing swords and use "cartoony" weapons (e.g., cannons, guns, explosive barrels) to shoot pellet-like projectiles at pirates, giant squids, skeletons, and enemy soldiers. Gunshots, canon fire, and battle cries can be heard during the somewhat frenetic combat; enemies burst into Lego pieces when defeated. Players occasionally engage in one-on-one swordfights—characters must deplete opponents' heart meters to win. In one cutscene, a pirate pokes a character in the belly with his sword, causing him to let out a comical yelp.
