Rockstar have revealed the PlayStation Portable will also visit the oriental themed area of Liberty City with Chinatown Wars making its way to Sony's handheld system after a successful outing on the Nintendo DS.

"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 Sam Houser, Founder of Rockstar Games. "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."

According to the press release, the PSP update will feature new missions, a clearly revamped game engine to support system's widescreen and extra power and will hit Australia and New Zeland store-shelves this Spring.
