Spike Chunsoft and tri-Ace have announced plans for a Exist Archive: The Other Side of the Sky collaboration with tri-Ace-developed, Square Enix-published titles Star Ocean: Integrity & Faithlessness and Valkyrie Profile.

Details on the collaborations have yet to be made clear, but they’ll start rolling out in January, so expect more information soon.

Exist Archive: The Other Side of the Sky is now available for PlayStation 4 and PS Vita in Japan. A western release has yet to be announced.
