The initial batch of copies of XIII released last week in include a special campaign code for the upcoming beta of Final Fantasy XIV on reports Siliconera.

For those Japanese gamers hoping to access the Final Fantasy XIV beta on PS3, that code will be essential. Applying for the 2010 beta requires a campaign code; that's only for the PS3 version, whereas the beta will be open for general applications.

Additionally, the key grants a special in-game item to be used when the massively role-playing launches late next year.

There's no word on whether we can expect similar codes in and copies of Final Fantasy XIII when the game ships on March 9.
