SEGA has announced that Sonic Frontiers has sold more than five million copies, marking a significant commercial milestone for the 2022 game. The achievement suggests continued interest in Sonic’s newer open-environment approach and intensifies attention on what the franchise’s next mainline release may be.

Frontiers sold 2.5 million copies in its first month, meaning it took roughly three years and eight months to double that figure. To mark the milestone, SEGA has made the Sonic Adventure 2 shoes available to all players; meanwhile, fans are speculating about a possible sequel or remasters of older Sonic Adventure games, although no next game has been confirmed.
