It's time to return to Liberty City, the town where all the rules were broken as Grand Theft Auto 3 revolutionized gaming and made the GTA series the biggest franchise on the planet. The PlayStation Portable edition is an all-new game set in the seedy, sprawling underworld of Liberty City. Just when you thought San Andreas was all you needed in your gaming life, Rockstar today announced that it is working on a brand new Grand Theft Auto title for the PSP. As youd expect from the highly secretive Rockstar, little is known about this latest in the GTA series except that it will take place in the streets of Liberty City (from GTA III) and that it is being developed by Rockstar Leeds.
