The size of the game area is smaller than San Andreas.
Transport will be suitable for getting around a city, so there are no planes, but choppers will return.
The main protagonist is Niko Bellic, a man of Eastern European extraction who has come to Liberty City to find his fortune.
Niko’s main contact is cousin, Roman, who runs a taxi firm and has been exaggerating his success.
The structure of the missions will be different - by using a mobile phone as a HUD, the gamer will be able to contact characters and be more proactive when getting information and jobs.
The police will be tougher than previous GTA games as Rockstar wants to reflect the idea that it’s harder to be a criminal in the modern era, thanks to advances in crime prevention.
