Would you be willing to answer a few brief questions about PlayStation Forums?
Just go:News ----> All ----> Find All Stars Battle Royale's image and click on it ----> Select PS3 version----> Buy the "Costumes Pack" ( €/£ 0.00) ----> ? ----> Profit!
My proof (I'm European):
No, I just downloading them. I'm EU. I'm from Italy, I think the UK's store is not updated.
I juts checked. they arn't there. then again, this is the american playstationstore were talking about, and we hardly ever get any special stuff that isn't supposed to be there. And don't worry, I'm positive they'll come out officially eventually.
