GTA IV

Niko Bellic, Serbian Russian, former employee of a top-end Russian import/export company who smuggled people, killed people and even brought guns, drugs, prosititutes and young women into other countries around Eastern Europe and Asia.

After a mistake with his former employee, Ray Bulgarin, Niko decides to move away from his home. He heard about these wild things that his cousin, Roman Bellic, used to get upto. Roman said he has a mansion, fancy sports cars, flashy clothes, loose women and other exploits. The only problem is... Niko doesn't know what other skills he has; except for one useful and powerful skill... killing people.

Enter Niko Bellic... the main character of Grand Theft Auto IV.

My Thought
-----
I think that Niko's story in GTA IV is kind of a rough one at that. He goes through an awful lot and despite his cousin's issues, Niko has to deal with his cousin's terrible gambling problems. It's a good example of what would happen if you did bad gambling and end up in debt to mobsters who will stop at nothing to chase you down.
On the other hand, Niko has an important skill that some employees would employee him for. It's kind of the same reason why one of the largest secret organizations has employed Agent 47 to be a useful asset to their company, Niko would be useful to some important and large secret government agencies.
Niko actually works for the Liberty City National Security Agency (acting as the United Liberty Paper Merchants Company Limited).
If you call them up during the game, you'll hear the woman saying that their are no operatives at the phone. Same as James Bond who works for the British Government (acting as Universal Exports London Limited) and he's a operative aswell.
So here's your real answer - Niko Bellic is a secret agent.
