As with all Grand Theft Auto games, GTA 4 promises an epic story with a full range of characters. The list below is based solely on screen shots and videos of the game thus far as well as any details from previews and will be updated with the full list, once the game is released.

Niko Belic

Niko Bellic is the protagonist and player controlled character of Grand Theft Auto IV. He is from Eastern Europe. Niko is guilty of committing previous criminal acts in his life and wishes to escape his past and his home, where he has currently been having issues. He is persuaded by his cousin Roman to move to Liberty City where he lives the "American Dream" and Niko falls for the deception and arrives in Liberty City by boat.

Roman Belic

Roman is Niko's cousin. He’s been living in Liberty City pursuing the American dream: fast cars, women, hot tubs, and luxury condos. At least, these are the things he’s been telling Niko about. Instead, he operates a taxi stand in Broker. A born optimist and a bit of a fantasist, Roman dreams big while he and his girlfriend, Mallorie decide whether to take each other seriously.

Elizabeta

For 10 years or more, Elizabeta has been a successful drug dealer in Bohan - successful because she kept things low-key and paid off or killed the right people. She knows that a crackdown on drug dealing is going to put her under scrutiny, and that her own narcotic consumption has spiraled out of control, making her dangerously paranoid and delusional.

Vlad

In Vlad’s own mind he is a supremely powerful gangster who runs the Hove beach neighborhood of Broker with an iron fist, and doesn’t take crap from anybody. In reality, he’s a low-level Russian hood who’s trying to gain favour with more powerful criminals, while he runs minor protection rackets and talks a big game.

Manny

Manny is testament to the fact men can be reborn. Once a hard living hoodlum, who was there (and involved?) when people invented graffiti, hip hop, and breakdancing, he never wanted any credit - it wasn’t about ego for him. He’s now a man transformed and all about one thing: cleaning up the neighborhood, the kids and the streets. To prove it, he's having a documentary made - about himself, to record his struggle.

Little Jacob

Little Jacob is a Jamaican gun dealer from Dukes (a.k.a. Queens) He sells you weapons from his trunk.

There is no other information known about Little Jacob, other than that he is involved in missions early on.

Brucie

Anyone who thinks modern man is having an identity crisis should meet Brucie. Brucie’s a serious fitness enthusiast, car nut and self appointed VIP. He’s also proof that sometimes, delusional white idiots can take the hip-hop thing a bit far. He's loud, he's proud and he's going to make sure you know just how much money he's got. He lives life large, just like men do in the magazines he reads. He’s got nothing but the finest women, cars, lifestyle accessories and anabolic steroids.
