Old topic but people need to be aware of this issue.
Tried logging in this morning (August 1st, 2013)
I could setup a Rumble match just fine, but news feed was not available and CC automatically doesn't work. Not sure if it's the usual garbage servers, or if the CC is in fact closed down.
If some people could check this on their own time and see if they can get through into CC we can clarify whether or not this game has unachievables.
PS: The WWE '12 servers are still working as of today and are LIGHTNING FAST, much better than WWE 13's actually. I was amazed, lol.
