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, skeletons, hostile natives, and enemy soldiers. Gunshots and battle cries can be heard during the somewhat frenetic combat; enemies burst into Lego pieces when defeated. During some sequences, players use a targeting crosshair to fire cannonballs at enemy ships; in one level, players use this same first-person perspective to shoot cannonballs at a giant squid, resulting in brief explosions. Some cutscenes depict instances of slapstick humor: a pirate kicking a character in the crotch; two male pirates wearing women's clothing and slapping their buttocks (amid catcall whistles).
