New GTA IV Details from Game Informer

Today I got my Game Informer Magazine which included this new information:

1. "...Grand Theft Auto IV does in fact feature a new targeting system - one that seems to be designed to please everyone. By holding the left trigger, the view switches to over Niko's shoulder. If you apply a click of the right analog stick, you'll zoom down the scope for precision targeting...If you don't want the game to aim for you, you can depress the left trigger halfway for free over-the-shoulder aiming..."

2."...carefully placing a rocket launcher shot so that the rocket skips off the ground..."

3."...You can also target items in the environment for more entertaining kills, such as a physics-enabled plank on which an enemy may be standing..."

4."...The enemy AI doesn't have the ability to throw back grenades (which Niko can "cook" by holding for a longer time), but they can play dead if they only have a sliver of life left. When you least expect it, they may pop up and open fire again..."

5."...Be sure to take at least two weeks of vacation time, as that's supposedly how long it's going to take to see everything in this massive title..."
