Yakuza: Dead Souls is an action-adventure/survival horror video game, developed and published by Sega exclusively for the PlayStation 3. The game is the sixth installment in the Yakuza series. The game's concept and keyword is "destruction"; a promotional image for the game showed the series' main locale, Kamurocho, in ruins. The game is set during a zombie outbreak in Kamurocho after the events of Yakuza 4, though the game itself is not part of the series' official canon. Eschewing the previous games martial arts based combat system the battles in this game instead focus on guns. Despite the zombie outbreak the series' trademark free roaming and side activities are still present.
