Flatline Emergency Notification Tone.

Example Video:

Just a quick, simple modification I made to the "All units" and "All units, All units" dispatch file for immersion purposes. It includes a flatline emergency alert tone used by some Fire and Law enforcement agencies to gather the officers' attention. The files themselves are not commonly used by the GTAIV dispatcher, so they will not be annoying or overdone in the game itself.

TO INSTALL:

Go to: (Install directory) Grand Theft Auto IVGTAIVlcpdfrAudioPoliceScanner. Locate and backup the original "ALL_UNITS.wav" and "ALL_UNITS_ALL_UNITS.wav". Replace these files with those you downloaded.
