Sony chief executive officer Kenichiro Yoshida unveiled at the CES tech show in Las Vegas the Vision-S 02, a new version of the firm's first prototype that has begun road testing.

With assistance from Sony, Citibank and Japanese law enforcement, FBI investigators were able to obtain the private key, equivalent to a password, needed to access the bitcoin address.

Sony says it recommends playing the title on PS4 Pro or PS5 for the best experience.
