Kingdom Hearts Unchained χ has been downloaded over 2 million times in North America following its release on April 7, Square Enix revealed today. Players can obtain outfits and in-game medals based on Judy Hopps and Nick Wilde from Disney’s recent animated feature Zootopia in an event ongoing until May 15 to celebrate this achievement.

Launched in Japan last year as a free-to-play mobile game, Kingdom Hearts Unchained χ lets players take up their own Keyblade and travel across various Disney words. Along the way, players can collect, fuse and evolve hundreds of medals that contain the power of Disney heroes and villains to customize the attack style of their Keyblades, partner with other players in guilds to take down heartless bosses and much more.
