Rockstar has released a new trailer for "Grand Theft Auto IV," the next installment in the popular series, titled "Move Up, Ladies."

"Niko Bellic is an Eastern European immigrant in his mid-thirties, who has come to Liberty City to pursue the "American Dream". Niko was persuaded to move to Liberty City by his cousin Roman, who claimed in multiple e-mails to Niko that he was living a fabulous life, with two women, four hot tubs and fifteen sports cars; but he was in fact telling lies to hide his own failures.

Roman is the only person Niko knows in Liberty City to begin with, and is one of his major connections in the first part of the game. Niko is a tough character, whereas Roman is friendly. Roman is heavily in debt and a lot of people are after him. He desperately needs Niko's support, hence the reason he deceived Niko into traveling to Liberty City. They are constantly bickering. It is later revealed that Niko has also been avoiding other, as yet undisclosed, problems at home."
