MTV News previews Grand Theft Auto IV. MTV News writes:
So much can be expressed in a 90-minute demo. The Rockstar team demonstrated the game's new dynamic car chases, which weave in scripted events that are triggered if certain situations align. For instance, during a hot pursuit past the Liberty City airport, Niko had to dodge barrels that came tumbling out of a swerving van. Other special events not shown but mentioned by Rockstar include a gas tanker driving into a gas station, or a completely unrelated car chase involving other crooks and cops whizzing by. These events won't happen in completely predictable ways, and players won't see them every time.
News about travel in "GTA" includes the breakthrough that cars that Niko steals now have GPS systems. A yellow route will be drawn on the player's mini-map in the lower-left-hand corner of the screen to get them to a selected destination. Players that steal luxury cars will discover that the GPS in those vehicles can talk.
Rockstar showed the ability to get drunk. This made Niko's walking and driving controls wobbly and the camera so shaky that MTV News quickly asked to move on to the next feature. Niko has a cell phone and can go to Internet cafes to search the Web. Stealing a police car provides access to a police computer that can be used to find suspects. The developers talked about enemies playing dead. Some things were left out. The Rockstar developers did not show multiplayer. They didn't show anything romantic.
