Grand Theft Auto IV (GTA 4) puts gamers in an all-new version of Liberty City, a living, breathing environment inspired by the greatest city in the real world -- New York. Playing as Eastern European immigrant Niko Bellic, you'll find out firsthand just what it's like to be a strange person in an even stranger land.

Sure, GTA: San Andreas might've had a bigger environment to explore than Grand Theft Auto IV. But you've never seen a more densely-populated, detailed and engaging environment in any other video game, ever.

Not only will the GTA 4 main Walkthrough take around forty hours of gameplay to complete, but there are also tons of Side Quests, optional missions and jobs, and so much more, that finding it all on your own isn't only a daunting proposition. It's pretty much impossible.

Are you curious how to get through a mission with Little Jacob? Are you wondering why your techniques running jobs in Roman's cab just aren't working? Are you interested in making your relationship with Michelle last? You'll even find the DLC content.

This Grand Theft Auto IV (GTA 4) wiki guide answers all those questions and more. And if you can't find the answer you're looking for, feel free to add in your own knowledge to help others! The old GTAIII saying applies here, friends. Welcome to Liberty City, where dreams are broken.
