Square Enix celebrated the eve of Final Fantasy XV’s release with a special live stream, where we got to check out plenty of fan art, a giant childhood Prompto, and a cameo fight against company CEO Yosuke Matsuda.

The live stream took place to celebrate the hours leading up to the Japanese midnight release of the game, where various staff members got together to check out a special “Mystery Disc” demo that was made just for the event.

The above video, with translation and English subtitles provided by dominationkid w., gives us a look at the Mystery Disc footage that showed some appreciation for the many fan art that was gathered from Twitter, the return of “Plumpto” in a giant form, and a cameo fight against company CEO Yosuke Matsuda.

Final Fantasy XV is available for PlayStation 4 and Xbox One.
