I have been playing Modern Combat 2 for a while on my Motorola Atrix 4g, and recently a friend of mine discovered it on his iPad. When I went to try to play against him online, I was unable to find his account (even when using the "join a friend" feature). I can very easily play someone who is using an android, however, I am having trouble trying to play across different platforms.
Is the online multiplayer mode for android different from the multiplayer mode for the iPhone/iPad?
