Seemingly following the footsteps of Sonic Mania, a listing on South Korea's media classification board disclosed an unannounced "Sonic Origins Plus."
Per Gematsu, "Sonic Origins Plus" could mean an add-on to 2022's Sonic Origins, which very likely means that new additions will be coming to the title.
In 2018, hit game Sonic Mania was released in physical media with additional content as Sonic Mania Plus, leading some fans to speculate that the same thing could be happening with Origins.
