The last two Grand Theft Auto games to be released on the PSP/PS2, Liberty City Stories & Vice City Stories, are set to be re-released on the PlayStation 3's PlayStation Network. Both games were originally released in 2005 and 2006 for the PSP, with their eventual PS2 ports being released a year later, respectively. Both games also serve as prequels to their respective city; Rockstar Games have released the synopses of each title:

Grand Theft Auto: Liberty City Stories

The streets of Liberty City are in turmoil. Warring mafiosi vie for control as the town begins to self-destruct under waves of political corruption, organized crime, drug trafficking and union strikes. No one can be trusted as Toni tries to clean up the mess of the city's chaotic underworld. Deranged hit men, morally depraved tycoons, cynical politicians and his own mother stand in his way as Toni tries to bring the city under Leone control.

Forced to fight for his life in an odyssey that will shake Liberty City to its foundations, Toni must use any means necessary to secure his place in the leadership of the Leone family in a town up for grabs.

Grand Theft Auto: Vice City Stories

Vice City, 1984. Opportunity abounds in a city emerging from the swamps, its growth fueled by the violent power struggle in a lucrative drugs trade. Construction is everywhere as a shining metropolis rises from foundations of crime and betrayal.

As a soldier, Vic Vance has always protected his dysfunctional family, his country, himself. One bad decision later and that job is about to get much harder. Kicked out onto the streets of a city torn between glamour and gluttony, Vic is faced with a stark choice - build an empire or be crushed.
