This weekend, we saw the announcement of Sumioni: Demon Arts for PlayStation Vita. Today, Namco Bandai released a new trailer for developer Acquire's other Vita launch window game: Shinobido 2: Revenge of Zen, a game that has stealthy ninja action, and, apparently, kind of a lot of voice acting. We'd expect ninja to be more reticent.

Shinobido 2 will be a launch-day release in both North America and Europe, shipping February 22.
