The official PlayStation Japan YouTube account has released a new trailer teasing an upcoming PS Vita exclusive from a third party. It appears to have a horror element if the trailer is anything to go by. There is also a teaser site in the description, though there is not much on it currently. This game is rumoured to be developed and/or published by Experience Inc as the site domain is registered to a “Hajime Chikami,” and that is the name of the CEO of Experience Inc.
