Yakuza: Dead Souls, known as Ryu ga Gotoku of the End (龍が如く OF THE END) in Japan, is an action game developed and published by Sega for the PlayStation 3. The game is part of the Yakuza series and was intended for release shortly after Yakuza 4, but was delayed due to the 2011 tsunami. Dead Souls combines the Yakuza universe with a zombie outbreak scenario.
