Sony Japan unveils Panopticon with an enigmatic trailer

Sony has released a trailer for its new sci-fi adventure Panopticon, currently in development at its Japan Studio.

The two-minute trailer shows a cel-shaded world of robotic dragons, futuristic London, and branded humans with identification numbers. No platforms or dates are mentioned in the trailer, and the mysterious cutscene-heavy footage does not clearly specify what kind of game Panopticon is going to be.

A teaser site has also been created, showing a countdown to May 21--suggesting more information will be given on the game the same day Microsoft unveils its next-generation Xbox.

Sony's Japan Studio is also currently at work on PlayStation 4 platformer Knack, which was announced along with the console back in February.

Sony would not comment on the game when approached by GameSpot. Last week the company promised some "intriguing" announcements on the horizon.
