Nothing lasts forever, least of all multiplayer game servers.
As of December 4, 2016, the online services portion of Batman: Arkham Origins will be retired We thank those that have joined us to battle over the last 3 years. The Single player campaign may still be played and enjoyed offline.
End of an era. This may be my favorite multiplayer mode of all time, and I was part of a very small community who played for several years. I’ll begin holding out hope for an HD remaster with functional multiplayer. Make it happen!
