Hello everyone, i want to know if this amazing game is multilanguage (i'm italian) for ps3! thanks

Supportet languages are English, French, German and Spanish, afaik.
At least there are trailers in these languages.

uhm i never heard multi4 games! i hope is multi 5 because there is also italian trailer

Well, if there is an Italian trailer (with Italian voice-acting) the game is most likely localised for Italy as well.
