The realchainsaw1.0.zip file you have requested: Mods / Sounds / Real Chainsaw - 742.15kb is not available. Perhaps try browsing all files for the game Doom III and upload any files you want to share or are missing. This is the only information we could locate:
The Real Chainsaw sound pack replaces the Doom 3 chainsaw sounds with a louder, more aggressive version recorded from a real chainsaw. The key addition is a real, much longer idle sound complete with throttle blips and carburetor burbling, plus better startup and shutdown sounds. The hit sounds have also been changed in an attempt to approximate the sound of a real chainsaw bogging down in material, as was done in the original Doom.
