THQ today announced that the Saints Row demo is now available for free on Xbox Live Marketplace, featuring a small part of the single-player mode, including character customization. Saint's Row is a third-person action that sets the player as a member of the Third Street Saints, a gang trying desperately to take back the streets from three rival gangs that hold the city. The game promises highly detailed visuals, no load times and the first ever open-world online multiplayer. The release is scheduled for August 29th.
