Grand Theft Auto IV: "100% Club" contest extended by fortnight at Rockstar Games' Social Club

Dedicated Grand Theft Auto IV players will be pleased to know that the "100% Club" contest at the Rockstar Games' Social Club has been extended by a fortnight.

The competition, which challenges players to receive 100% completion in the single player section of the game, will now end May 19. Those who manage to pull off the weighty task will be awarded with a "Key To The City", a limited edition Rockstar Games branded key with a $50 value.

Data is verified via Xbox Live and the PlayStation Network, dependant on which console the user is playing the game on. Entrants must be sure to have their online ID linked at the Social Club in order to upload game progress.

Grand Theft Auto IV was released April 29 on both the PlayStation 3 and Xbox 360 video game systems and has so far sold over USD$500 million.
