It's always sad to see a server close down, and this time it's the turn of WWE 2K14
to wave goodbye to its server. Announced in a tweet
from 2k Support, they announced that the game's servers would be shutting down on "10/31/15 at 11:59PM PST, ending online matches & community creations". Unfortunately, with no servers, this will mean all of the game's online achievements will become unobtainable, so you have just under a month in which to get them.
The game's servers will be shut down on 31st October, so make sure you get the online achievements done while you have the chance.
