Sonic-16 is an unreleased spin-off game in the Sonic the Hedgehog series developed by Sega Technical Institute for the Sega Mega Drive. It was meant to be set in the continuity of the Sonic the Hedgehog television series.


Sonic-16 was put together shortly after the completion of Sonic the Hedgehog Spinball by Peter Morawiec and John Duggan.[1] The demo was dated November 1993. However, probably due to the slow pace of the demo, Yuji Naka gave the demo for the game a thumbs down, leaving Sonic-16 to never be fully developed.

Sonic-16 was meant to be 16 megs (2MB) while the artwork was to be designed to reflect the style of the Sonic the Hedgehog television series instead of the art style used for the games in the Sonic the Hedgehog series. Also, the sprites and level artwork would be overall larger in size than those used by the Sonic games released around that time. Also, while the speedy tempo of the trademark Sonic gameplay appeared to have been slowed for this title, Sonic-16 was meant to include fast-moving segments as well. in addition, in order to make the game tie more into the television series, Sonic-16 was going to be more story-driven than previous Sonic games.

According to Chris Senn, Sonic-16 was supposedly another phase of the canceled Sonic X-treme video game.[2]

Eventually, a video demo demonstrating Sonic-16 was released. In this demo, Sonic is shown residing in a level resembling Robotropolis, complete with enemy cameras and Swat-Bots. Upon reaching the end of the level in this demo, Sonic defeats two Swat-Bots and meets up with Sally, who opens the door to the next room which Sonic then enters.

Sonic-16 was presented as a 2D side-scroller. In gameplay, Sonic moves slower than he normally does in typical Sonic games, but possesses in return new moves suited for this speed. Some of his moves include the Ring Attack, which has Sonic grab the Rings from his life bar and throw them like projectiles at enemies in order to destroy them, the Buzzsaw, which is a midair move where Sonic spins around in order to clear out obstacles, and the Spike Blast, which is another midair move where Sonic shoots quills that can damage surrounding enemies in different directions.

In terms of movement, Sonic can move both left and right, as well as up and down thanks to a widened vertical perspective in the levels. Sonic can as well hold his back to the wall to evade detection and peak around corners. He can similarly grab and pull himself up onto ledges.
