Sega published satirical zombie horror title Yakuza: Dead Souls exclusively for PlayStation 3 in 2012. The Japanese title "Ryū ga Gotoku: Of the End" is a play on George A. Romero's Night of the Living Dead movie franchise.

The non-canonical Yakuza series entry stars protagonists Kazuma Kiryu, Shun Akiyama, Goro Majima and Ryuji Goda. Set one year following the events of Yakuza 4, a deadly plague transforms the inhabitants of Kamurocho into zombies.

Music for Yakuza: Dead Souls is composed by Mitsuharu Fukuyama, with Hiroshi Furukawa and other artists. The two-hour, two-volume soundtrack for Yakuza: Dead Souls is streaming on Spotify and Apple Music.
