Player progression through the game directly affects the presence of their friendly gang, the 3rd Street Saints. The game world is subdivided between districts, such as the Red Light or Downtown districts, each comprising several neighborhoods. Each neighborhood is controlled by a rival gang, but as players complete missions the 3rd Street Saints will take over neighborhoods, causing street members of the gang to spawn there. The pause menu displays a large map of the game world, which allows players to view a graphical representation of the streetscape, and a color filter over each of the neighborhoods represents the gang whom control that neighborhood (purple for the Saints, yellow for the Kings, red for the Carnales and blue for the Rollerz). "Saints Row" features an in-game GPS navigation device, which allows players to set waypoints with a directional line indicating the quickest route to the marked destination. Players may enlist allied forces, referred to as homies, to aid in combat. Street members of the 3rd Street Saints may be summoned, or players may call up unique homies on their in-game mobile phones. Players can further utilize their mobile phone to contact services such as taxicabs, contact other numbers scattered throughout the map on billboards, or input cheat codes.
