Although Onechanbara Z2: Chaos is certainly fun to play through, it does fall short in too many ways to look at it as much more than an average experience. If you enjoy button mashing, fan service laden zombie slaying, this game is for you. For everyone else, you may want to do your research before committing to this title.
I recognize the way the gameplay could be fun to other people, but I ultimately did not find it good enough to carry the entire experience. There is challenge, but it doesn't feel fun. With a lacking story, at best average graphical presentation, and gameplay that falls short, I can't find much that would appeal to those who aren't already fans of the Deception series.
I did like the game, and were it longer, I would have no trouble rating it higher. The short experience is the one thing that I feel holds the game back, but the overall experience is certainly worthy of a play through. I find it easy to recommend this title.
