is it chipped ?
Nope its a region free game (so i have read) meaning you can use USA or EU on your 360
Then why do u get a US and UK Version?

you could always download and flash your dvd rom for free and then buy the R150 versions. saves you R 300 to give to telkom. but dont blame me I dont even own a 360.
