ONE PIECE PIRATE WARRIORS 4 continues the musou-style action series, letting players control an expanded roster of One Piece characters as they battle through massive enemy hordes. The story reworks major arcs from the anime into large-scale, one-versus-army combat.

Players unleash powerful special attacks and team up with allies to clear waves of enemies across story-driven missions. It's aimed at fans of One Piece and hack-and-slash musou combat.
