Gamers who register their PSPgo between October 1st and October 10th will get a free download of Gran Turismo PSP.
The announcement was made by SCEE president Andrew House during the Sony Gamescom press conference. House said it is the full game, and not a demo, and will be available to all European consumers.
The game is due for release on October 1st alongside the PSPgo.
The firm also announced a range of new colours for its PSP 3000, including Lilac, Pink and Green.
