Hi everyone it's Xebs, SQUARE-ENIX have announced on the Kingdom Hearts Unchained χ website, that Kingdom Hearts Unchained χ will be available on iOS and Android devices in September. Also, by pre-registering you can access "awesome" wallpapers for your iOS or Android phone.
Unfortunately, for the meantime it's only the Japanese version with a release date. There's no word on a release date for the western version. However, I'll keep you guys informed.
