Nexon and Sega have announced a collaboration in KartRider Rush+, a free-to-play kart racing game for mobile devices, that will see Sega icon Sonic the Hedgehog join the game from now until June 30.

　　Sonic will team up with KartRider's heroes Dao and Bazzi in a quest to collect as many shards as possible, which can then be exchanged for in-game items. Sonic-themed daily quests will also be available during the event, and completing them will earn players the Blue Blur as a permanent character in the game.

　　KartRider Rush+ is a free-to-play kart racer where players can race in single-player story mode or a selection of competitive multiplayer modes, including ranked races and time trials. The game is available now on iOS and Android devices.
