Ken McKown writes: The Onechanbara series has always been a weird and peculiar one. It wears its gratuitous violence and sexual tendencies on its sleeve. It has also not been a very good game in general. The previous entries all relied on their shock factor, as opposed to crafting a fun game play experience. The latest entry in the series seems to finally be correcting those issues. The combat system is deeper, and much more refined. There is plenty to unlock and customize, and the upgrade system is kind of addictive. However, that doesn’t change what people come to Onechanbara for, and Z2 Chaos is by far the most gratuitous title in the series to date.
