The first part of the digital tie-in prequel comic for Sonic Frontiers titled “Prologue: Convergence” was released today via Sonic the Hedgehog’s Social media accounts much like the Sonic Forces digital comics. However, it should be worth noting that unlike the Sonic Forces prequel comics this new two part comic doesn’t contain any crucial story details that won’t appear in the main game’s plot, according to writer Ian Flynn, the comics will just be supplementary material, or as Ian said himself, more like gravy rather than a full meal.
