Niko has a nice jab
I like it, especially the new combat/weapons system.
Kind of sucks that you fly out of the windshield when you hit something head on while driving. Can no longer do some insane stunts. The new way to escape police is kind of a bummer too. It is more realistic, which is cool..but takes away from some of the crazy things that could be done in other games or at least makes them much more difficult to pull off.
I played it for a couple hours today. Put in the weapons cheats and used to RPG to blow up some cop cars and police helicopters. Insane effects on explosions in this gam!
