If you are an Onrush fan, then its real bad news for you.
Codemasters and Electronic Arts has made the big annoucement that the online servers for Onrush will shut down on November 30. With the servers shutting down, it means that any online achievements you have achieved till date will be unobtainable after the November 30 date. But if you want to continue playing, offline modes will continue to be available.
So you have only two more months to play Onrush using online modes. Make the most of it!!
