In this fourth installment in the Wild Arms series, gamers play as the 13-year-old main character Jude Maverick and adventure with the heroine Yulie, a handsome but cowardly man named Arnaud, and a gray-haired swordswoman named Raquel. Wild Arms: The 4th Detonator adopts a new battle system featuring hexagonal cells similar to a strategy game, and also adds some extra action game elements in the field screen.
