Rockstar Games has announced that it is working on a PSP version of DS game Grand Theft Auto: Chinatown Wars.

The publisher's Leeds-based team is working with Rockstar North on the title, with a view to releasing it in Europe and the US this autumn.

Development will particularly focus on utilising the PSP's widescreen graphics, enhanced lighting and animation power, while new story missions will also be introduced.

"We're proud to extend this truly unique handheld Grand Theft Auto experience to PSP and offer a downloadable version of Chinatown Wars for PSPgo," said Rockstar founder Sam Houser.

"Rockstar Leeds has shown incredible talent in creating games that raise the bar in terms of depth and innovation on portables, and with Chinatown Wars we have a rich, fast-paced, and incredibly addictive entry into the series."
