most games will feature the language in which the PS3 is set too. but most games only have, german, italian, spanish, french and english... I would be quite surprised if it was in portuguese too. infelizmente é assim
The uk version does not include the portuguese language, nor does it include any other besides english. There is indeed an uncharted 2 version which includes both portuguese voice and subtitles, but unfortunatetly it's not this one.
