Squeezing off a shotgun round at the driver caused blood to splatter across the inside of the windscreen (which was now riddled with tiny bullet holes) as the driver's body was knocked violently back in his seat before slumping forward with his head resting on the steering wheel, causing the car's horn to constantly blare away. The intensity and detail we witnessed in this split-second of gameplay left us utterly gob-smacked, and even a little guilty about whacking the poor guy - at least we put his car to good use. He would have wanted that.
It's also confirmed in the article that you can actually blindfire rocket launchers, a feature I presumed would just be for normal guns.
Cap someone in the leg, for example, and you'll see their limb flung back as their body loses balance and topples over. Shoot them in the face and their head will snap back with great force, before their body crumples lifelessly to the ground. Euphoria makes all of the typical GTA sandbox-style antics you're used to seem fresh again.
Read the whole thing over at IGN - if it doesn't make you more excited about this game I don't know what will. Also, feel free to comment on this post and add your own ideas to the list of 'things to do when you get GTA4'.
