Arashi: Castles Of Sin might not go down as VR’s answer to Tenchu, but it gets a lot right with its open-ended level design and its fantastic realization of Feudal Japan. It’s a rare VR game that gives you genuine choice in deciding how to get from A to B and, when it works, captures the slick elitism of becoming a ninja. But it’s let down by clumsier elements, like bugs, bad enemy AI and underwhelming sword combat. Even these dark forces combined aren’t enough to derail the fun sneaking at the core of the experience, but there’s plenty of room for Arashi to improve with a potential sequel.
