As it was previously announced by Rockstar, a new trailer for GTA IV titled "Move up, ladies" is available. The new trailer shows much more than the previous two and it definitely brings even more attention to the next sequel of the GTA franchise.
The new trailer shows a lot of interiors, a bit of Niko's and his cousin Roman's background, a lot of hand-to-hand combat sequences. and a great track called "King Ring" by Serjoga, the popular Russian rap artist. Anyway, the new GTA is shaping up nicely and getting even better and better. The new trailer certainly brings even more excitement.
The new GTA IV is still scheduled for Q2 next year. You can check out the new trailer here.
