3: there must be no mark on xbox Market USK be special the PEGI logo
4: As I said German paypal and credit card does not go on ösi account but only the Xbox prepaid card for example. 25 credits.

Do you want more then game gets even a special tip Dead Iceland, Iceland riptide Dead, Dead Rising, Dead Rising 2, prototype 1 & 2 Uncut and available for One Dying Light and more can be downloaded only to Austrian account. Hope I have helped you, and wish you all a lot of fun with Left 4 Dead 2 uncut ps.
