bought this from an online company about 2 years ago dont play much anymore.i had changed the shells out a bunch of times,shell on it is kinda crappy,easy to switch if you have the tool.has blue & orange led's around the xbox button instead of green,3 mode rapid fire great for cod zombies.not sure if it works on the newer call of duty's online multiplayer i kno companys and people keep making newer updated ones.if need be you can ship your shell or controller to me and ill switch the shells out and ship back.paid $70 for it. asking $30
