In One Piece: Assault on Marine Ford, players relive one of the most epic battles in the One Piece saga. Ace has been captured by the Marines and is set for public execution on Marine Ford Island. Whitebeard, determined to save his adoptive son, has assembled a powerful fleet of pirates to launch a daring rescue mission. Players choose to either join Whitebeard's pirates in their mission to free Ace by finding the key to his handcuffs and helping him escape, or side with the Marines, tasked with eliminating Whitebeard and Ace to maintain justice.

With strategic team cooperation and intense combat, players must fulfill their objectives or outlast their opponents on the battlefield. Victory is determined either by achieving mission goals or by having the most characters on the board at the end of the game. Designed for 2 to 6 players, this game captures the essence of large-scale battles and tactical decisions as players vie for control over Marine Ford.
