Rockstar Games has announced via its Twitter account that Grand Theft Auto: Chinatown Wars will be released for PSP on October 20 - presumably it'll be October 23 in the UK.

As was previously announced, the game will be available at retail on UMD and digitally via the PlayStation Store.

Grand Theft Auto: Chinatown Wars follows the story of Huang Lee, a young Triad who travels to Liberty City after the mysterious death of his father. Within the game, players will navigate their way through the streets as they uncover the truth behind an epic tale of crime and corruption within the Triad crime syndicate.

Based on the title already available for Nintendo DS, the PSP version will feature upscaled widescreen graphics, enhanced lighting and animation, plus all-new story missions.
