In the first hours of Yakuza: Dead Souls, I witnessed the fictional Kamurocho neighborhood of Tokyo's red-light district becoming ravaged by a zombie nightmare, with wrecked buildings, flaming cars, and thousands of hungry undead taking to the streets.

With the help of a DVD store's secret weapons cache, altruistic loan shark Shun Akiyama becomes a dual-pistol-wielding killing machine, cutting a path through the horde of former businessmen, students, and gangsters to get help for his sick assistant Hana.

Though the premise seems (and is) absurd, and there's little sense to making a zombie shooter out of a series best known for its uncanny representation of a realistic Tokyo, I couldn't help but appreciate the care Sega put into setting up the adaptation. Every change to gameplay, environments, or story required to adapt the game into a shooter shows evidence of deliberation and forethought. It's not just a matter of adding zombies and guns. Sega took its assignment very seriously, even though Yakuza: Dead Souls delivers its entertainment in a campy, b-movie way.
