"GTA: Episodes from Liberty City is a standalone expansion for Grand Theft Auto IV, which was until the release of Modern Warfare 2 the highest grossing entertainment title in history. Both episodes are available as individual DLC for GTA IV, but are also available as a bundle on store shelves, and do not require the original game to play, however, it certainly helps to have played the original.
What do the following have in common: William Wallace, Niko Bellic, South Africans since 1994? That was an easy one, the answer is freedom! And that is exactly what you get in the Grand Theft Auto games. Although true freedom is quite a stretch when it comes to games, as you quickly find out in this particular series. It does create quite the illusion though. Liberty City is, as the name implies, again the venue for this adventure that takes place during the same time as Niko Bellic's time there. You get to go where you want and do what you want, but not without consequence. The police will act harshly on those who transgress."
