Nope, you can't. There is no crossplay between platforms of any kind. Even the X1 can't play with players on the 360. It would be awesome to have such a thing implemented. The community is going to be a lot larger. PC wouldn't work since it's got stuff that consoles don't.
Since the dawn of online gaming companies have never ever since ventured on the idea of crossplay. You'd think that this year 2014 we could've at least have the luxury to do that. If that happens though the gaming community would be one hell of a riot, I'm not sure about the complexity of it but I think if there's a service that would allow it, kind of like Origin or something, it would be possible, but then again, it might be more complicated as we thought.
That's actually not true at all. Numerous games have included cross-platform play online, including Kane and Lynch: Dead Men, Shadowrun, and Portal 2, among others. Portal 2 did it pretty successfully. It's not that hard to do, but it does require agreements from everyone involved, which isn't easy. Technical aspects of cross-platform play couldn't be easier, though, as far as I've heard. I think we'll see a truly successful cross-platform game in the near future, but I doubt it will happen within the next year.
