If you are an IOS user and have multiple accounts linked to your Gamecenter Account... wether it be Crime City, Modern War.. or ANY other games
!!!!!!!!! DO NOT UPDATE YOUR DEVICE !!!!!!!!!!!
Apple have officially announced that Gamecenter will no longer be available on the new release, due in the next week or so.
This an Apple issue and unrelated to Gree or any other games developer.. Spread the word amongst your teams and friends. ☺
Will update when find out more!
It may be supposrted in a different form but as of yet, there is no clear information on it.. anywhere... so be careful
