Rockstar Games has announced that GTA: Chinatown Wars is on its way towards the PSP as both a downloadable title and in UMD format. Apparently the game was so successful on the DS they decided to port it.

“We’re proud to extend this truly unique handheld Grand Theft Auto experience to PSP and offer a downloadable version of Chinatown Wars for PSP Go!,” said Rockstar boss 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.”

CEO of Sony America, Jack Tretton, was equally delighted with the news: “Rockstar’s work with the GTA series has been an enormous part of the success of PlayStation platforms.”

“We’re excited to welcome the critically acclaimed Chinatown Wars to the outstanding line-up of great games headed to the PSP platform this fall.”

It will probably sell better than the DS version.

Rockstar has confirmed that their portable romp in the GTA franchise will be released on March 17 in the US. Europeans will get their hands on the game 3 days later.

“Rockstar Leeds have once again created a game that far exceeds our standard for deep an innovative entertainment,” said Rockstar boss Sam Houser (brother of Rockstar VP Dan Houser).

“We are incredibly excited to share this enormous and uncompromising Grand Theft auto experience with DS fans.”

You can’t fault the man for being enthusiastic about their product.

Officially detailed today, the Xbox 360 exclusive GTA IV downloadable content, entitled “The Lost and Damned”, will include an entirely new side-story, new multiplayer modes, new weapons and vehicles… and even a new radio station.

“The Lost and Damned” will be the first of two episodes, and it will launch on the Xbox Live Marketplace on February 17. The side story will put you in control of Johnny Klebitz, a member of Liberty City biker gang The Lost, and will intersect with the main storyline in places.

“Making these episodes has enabled us to expand the narrative and the experience of interacting with a game world in really innovative ways,” said Rockstar’s Sam Houser. “We hope fans of the game enjoy the new way of experiencing life in Liberty City contained in this first episode.”

Well, when they said they were planning big, they certainly weren’t kidding.

This is what downloadable content should be.
