I got European call of duty Black ops II for wii u.This stuff's region-locked, by default. I think most cfws might be lifting the region lock though? Needs confirmation.
I hear depending on the game it might give you trouble though...
When I had a Wii U which was years ago I bought BO2 for it and I just couldn't get used to it. It wasn't as entertaining or interesting as the Modern Warfare games were.Im just get the USA version of cod black ops II.
