It looks like it's the Korean version. I know it's not region protected but are the menus, controls, dialogue and all of that in English?
From the product's description on its Play-Asia page:
Language English, French, Spanish, Italian, German
Boy, I certainly hope it's got at least English voicework. I could really care less what language the instruction manual is printed with.
I'll take my chances, but if anyone has any precedent about Korean versions of 360 games, thanks in advance.
