A lot of different news on Sonic Forces has been dropping these past 24 hours, and now word from Game Informer is that Knuckles, Amy Rose and the Chaotix can be heard communicating to Sonic on the chaos going on near them via radio. This likely puts them as NPC characters rather than playable, but they are in the game in some form. Still, “Forces” usually implies armies of some sort, so it’s possible the game has characters set in groups, but that’s just a theory.
Sonic Forces will be out this holiday season on PC, Switch, Xbox One and PS4
