Startup pr sound file

[EinEcki]

You can extract this sound from the video:

Go to your BF2 Folder mods/pr/movies and there you have the file pr_intro.bik

You can open .bik files by using a Bink video player which can be found here: Bink Downloads

Now you can record the sound while playing the video using a tool like Audacity which can be downloaded here: Audacity: Free Audio Editor and Recorder

You only need a couple of minutes for that.
