At last, after weeks of delays, Activision have at last released the Call of Duty Elite app they promised for Android. It came out on iOS a week ago and has proved to be very popular.
You will need to register a Call of Duty Elite account (it is free to register). Once you have you can evaluate your multiplayer progress with in-depth stat analysis.
Probably the greatest feature is the ability to customize your gun load outs within the app, then push them to the game. So if you've formulated a new killer setup at a spontaneous moment, no having to wait to get back on to your PC, PS3 or XBOX, you can do it right from the app.
