Yakuza 4

Yakuza 4 is a single player action adventure video game both developed and published by Sega for the PlayStation 3. As with the original title, Yakuza 4 takes place primarily in Kamurocho, but since the third game, three new locations have been added: the rooftops; which stretch across town, the back streets; known as Rojiura, and the underground; which includes sewers, parking lots, and shopping arcades.

Three new main characters are also introduced to join Kazuma Kiryu who has been the series' anchor since the original,while each main character also features an extra side-story mission, necessary to achieve 100% completion. Yakuza 4 also features a number of minigames, including pachinko, fishing, onsen bath, table tennis, hanafuda, and karaoke.
