I believe you mean the controller. You will need to buy a rechargeable battery.
No you can only play mw3 on xbox 360 (and pc and ps3 of course) not on xbox.
If it is the xbox 360 MW3 I dont think you can change how much gore there is.
Amazon is $51.99 delivered on December 7 2011 Walmart has Xbox 360 MW3 controller game bundle for $89.99 or PS3 Xbox 360 game for $51.96
The Call of duty mw3 game (saved games etc) are located in the memory settings.
With much difficulty.
No -_-
There arn't any.
$50 or $55 or $60
Nope. It wouldn't be good anyway.
Any version of MW3 is compatible with the COD Elite program. It doesn't matter if you use Xbox 360, PS3, or PC.
No it will only be on the PC PS3 and Xbox 360 and is available for preorder
The hard drive that doesn't work for the MW3 Elite game is most likely fried. You can contact Xbox to see if you still have your system under warranty.
