This page will list the confirmed information for the Grand Theft Auto IV game.
|Spoiler Warning: Plot and/or ending details are in the text which follows.|
- North America: Q2 2008
- Europe: Q2 2008
Grand Theft Auto IV will be powered by the Rockstar Advanced Game Engine, otherwise known as RAGE, which has been developed by Rockstar Games. RAGE graphics were also used in Rockstar Presents Table Tennis.
Grand Theft Auto IV will appear on both PlayStation 3 and the Xbox 360, released simultaneously. The game may also be released for the PC, as all the previous Grand Theft Auto games have been. A Nintendo Wii version is highly improbable due to the difference in power between the console and the PS3 and Xbox 360.
A Grand Theft Auto IV trailer for the Nintendo Wii was released on April 1st 2007 by Jordan Liles, the webmaster of Planet Grand Theft Auto, as an April fools. The trailer, which uses footage from Grand Theft Auto III and Tommy Vercetti as the protagonist, can be viewed on Google video. 
The protagonist of Grand Theft Auto IV is a man called Niko Bellic, believed to be from eastern Europe. During the trailer, released on March 29 2007, he said "Life is complicated. I've killed people, smuggled people, sold people. Perhaps here, things will be different..."
Grand Theft Auto IV will be set in Liberty City, which will be a different rendition of the city than seen in either Grand Theft Auto or the Grand Theft Auto III era. Liberty City has been confirmed as the only city in the game. The city is based around New York City, with many landmarks such as the Statue of Liberty being seen during the first trailer. However, evidence shows that the city will be called Liberty City.
- Liberty Tree, the Liberty City based newspaper from the GTA III era returns.
- An I Love Liberty City sign can be seen during the trailer, close to the Liberty Tree sign.
- A Liberty City Police Department police car can be seen in a Downtown-like area of the city.
- A Welcome to Liberty City sign can also be seen under the Liberty Tree sign.
- The Liberty Ferry Terminal, along with a boat saying Liberty on the right of the screen are seen in a dock area.
- A Platypus ship has the words Liberty City written on the back.
The year the game is set in has yet to be confirmed. However the Hearst Tower, or the GTA IV rendition, is visible in the trailer. The building was finished in early 2006, hinting that the game maybe set in 2006.
Episodic content has been confirmed for the Xbox 360 version. This was confirmed at the 2006 E³ during the Microsoft press conference. Peter Moore, head of Microsoft's Interactive Entertainment Business division, made the announcement that two downloadable packs of extra content would become available via Xbox Live. The episodic content was described by Moore as being 'epic', with Take-Two Interactive announcing that the content will become available during 2008. The actual date has yet to be confirmed.
Episodic content may become available for the PlayStation 3 version, although nothing has been confirmed. There are rumors that the content will be different to that confirmed for the Xbox 360.
The content will feature "hours of entirely new gameplay", not just cars and new characters. There has been no information on the price of the content, and the exclusivity of the content is vague in detail.
