"I only played this demo because there was no line for it. It turns out there was a reason for that. The demo was in some US urban city slum and the character you play is a woman decked in street gear. There is no mission or goal, you are just free to explore. I ventured into a building, which was at first quite nice as GTA IV generally restricts this, but I left pretty soon when I discovered there was nothing to do inside. I blew up a few cars, killed a few pedestrians and the whole scenario soon got out of hand although I had no problem killing the policemen sent to arrest me."
