The game was originally released episodically in digital form, and SEGA branded it as the fourth entry in the series even though it launched over a decade after 1994's Sonic & Knuckles.

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
