Developed by series creator Rockstar North and set in Liberty City, the latest installment in the enormously successful Grand Theft Auto series features a painstakingly detailed and life-like city for players to explore; a rich, immersive narrative experience; an original soundtrack highlighting the cultural eclecticism of Liberty City.

What does the American dream mean today?

For Niko Bellic fresh off the boat from Europe, it is the hope he can escape from his past. For his cousin, Roman, it is the vision that together they can find fortune in Liberty City, gateway to the land of opportunity. As they slip into debt and get dragged into a criminal underworld by a series of shysters, thieves and sociopaths, they discover that the reality is very different from the dream in a city that worships money and status, and is heaven for those who have them and a living nightmare for those who don't.

There is a virus sweeping through Grand Theft Auto IV turning many unsuspecting players into Zombies. If you've seen the special Zombie-with-yellow-briefs player skin running around during Grand Theft Auto IV multiplayer, then you may already know that the virus can be contracted in any and all multiplayer modes and is spread when an unsuspecting player kills someone who has the infection (BE ADVISED: The infected DON'T necessarily have to be wearing the Zombie skin, some show NO SYMPTOMS!).

The signes of infection are:

• Access to the zombie skin
• Having the Achievement "Let Sleeping Rockstars Lie".

With the all-new Viral Infection feature at the Rockstar Social Club, members can now see whether they are currently infected, the number of total global infections and the number of infectinos in the last 24 hours. Digging deeper, Social Club members can also browse a color-coded world map tracking the spread of the infection worldwide, including breakdown for all 50 US States.
