As of October 29th, 2013, 2K will no longer offer online support in WWE ’12. This means that while your game will still perform exactly the same offline, you will no longer be able to upload and download Community Creations content or play online multiplayer matches.
Please note that this in no way affects the online support still being offered to WWE ’13, and the upcoming WWE 2K14 – the first new WWE game under the 2K banner.
