EA's online services for all games will be offline for approximately two hours tomorrow morning from 6am, the publisher has announced.
The downtime is to enable the publisher to roll out an "extensive upgrade to our game servers".
This means players will not be able to play online multiplayer, or log-in to their games during this time. Those currently logged-in may be affected as well.
For UK gamers, downtime from 6am to 8am shouldn't present too big a problem.
