Oneechanbara: Bikini Zombie Slayers - It's not exactly bad, but it's clear Tamsoft was working on a low-buget. Ironically enough, the game is better than the earlier titles and the first HD outing,
Bikini Samurai Squad. The only flaw with BZS is that the game has motion controls only. They do work fine enough, but it still sucks Tamsoft nor D3 thought of putting in or adding in the standard control scheme with the Classic Controller, nor GC controller.
That said, the later entries releasing on 360, and then later on PS4 are much better games in terms of looks and combat.
Z: Kaguara (a sort of soft reboot) and
Z2 are the
DMC4 and
DMC5 of the franchise, and
Oneechanbara Origin is a remake of the first two games combined into one game, and has an anime look, instead of looking "realistic".
Origin's only flaw is the price for DLC/deluxe edition when not on sale, and the lip-synching is bad in the English dub. The dubbing itself is good, but the localization team clearly rushed to get the game out over seas without proper lip synching.
Z2 is still the best in the franchise.
