For starters, the post-credits scenes give us some clues.
In the first one, we’re introduced to Metal Sonic(s) and Amy Rose.
Then, the final one confirms that Shadow is still alive after the events of Sonic 3.
This comes to us courtesy of Tacit Sign Studio, who also worked on the first film.
It seems that many of the scenes depicted in the artwork made it into the final film.
The concept art for Amy certainly backs this up, as the background looks completely industrialised.
The console wars live on at the box office.
In any case, Sonic 3 is still in theatres.
It will launch digitally on January 21.
