PSP hardware is more advanced than Nintendo DS's, but Rockstar claims that the DS exclusive GTA: Chinatown Wars will be "much bigger" than its PSP predecessors.
"Grand Theft Auto: Chinatown Wars is much bigger than anything we have ever done before [in terms of scope]", said Rockstar Leeds president Gordon Hall.
According to Hall, Chinatown will feature "more odd jobs, deeper missions, and more moments of over-the-top action."
"We have a huge interaction with the Rockstar Social Club, a massive [narcotics trafficking] game that would stand alone on its own. The list goes on and on; this thing is huge. We are very proud of all of the PSP games we have made, especially the two GTA games, but this game is far bigger."
Chinatown Wars is due out in North America and Europe on March 17 and 20 respectively.
