We already announced yesterday Rockstar's plans to launch a new and enhanced version of the official GTA IV homepage. A few minutes ago the new site has been launched! There is not much left of the old homepage.
But the site has not just changed its design, it is full of new content: For the first time Rockstar Games presents the boroughs of Liberty City with a lot of new screenshots, videos and even a raw map of Liberty City that navigates you through the site. There you can see the boroughs being connected by bridges (as usual).
For further entertainment Rockstar Games added some mini games. One of those is a skill game, where you have to carry a can of Sprunk and prevent it from exploding due to too much shaking.
If that game is to thrilling, maybe take a look at LoveMeet. It has been created for the lonely hearts among you to get to know your real character.
The sections for Multiplayer and Music are not available yet. But nevertheless there is very much to explore! So go out and explore the world of Liberty City at Rockstargames.com/IV/.
