The Sonic Forces digital comic is a four-part digital comic series published by Sega that is based on the at-the-time upcoming Sonic Forces. Intended to promote the aforementioned game, this series is scripted by fan-favorite writer, Ian Flynn, and Sonic Team, and illustrated by Adam Bryce Thomas. Each issue features a short, self-contained story that serves as a prequel to the video game counterpart. With the exception of the fourth issue (which came out on the 7th of November, a Tuesday, the same day that Sonic Forces itself came out), all issues were released on a Thursday.

Retrieved on 13 October 2017. “Sergio: But first... how about that uh... how about that comic they put up today? / Aaron Webber: Yeah, well, we'll talk about in a little bit too, but there is a brand new Sonic Forces comic that went live. It shows a little bit of the backstory to what is happening inside the game, and it is one of a number of different stories we're gonna put out as we go up to launch. It's pretty exciting. / Sergio: That means it's canon. / Aaron Webber: Uh... Everything is canon, remember that.”
