PSInsider author writes: Onechanbara is a video game series hailing from Japan that has been around for sometime. The most recent release, Onechanbara Z2: Chaos, hit US shelves, having already been released in Japan last year, earlier this month. I acquired a copy and spent some time sitting down and playing it. After playing it, there is one thing I’d like to say upfront; this game is NOT for kids. There is a lot of fan service, some interesting language and a ton of blood and gore.
