This is definitely one of the few Star Wars games that got a soundtrack release, in this case it was a free release on the old Republic Commando website.

Any chance of that getting added to make it a more complete bundle?

That would certainly be very cool, but there may be rights' issues. For the time being, perhaps http://www.clonecommandos.net/ > http://www.clonecommandos.net/RepCom_Music.zip will suffice? (I haven't listened to it, though.)

You can always find the music on YouTube, also: https://www.youtube.com/results?search_query=republic+commando+soundtrack

You can find all music parts from the game in your game folder

\Star Wars - Republic Commando\GameData\Music they are ogg which you shouldn't have any problems playing from even most basic players like windows media players for example.

Funny cos I already have the music from my star wars soundtrack album. Some parts I specifically remember from the Starwars movies like where the tie fighters are chasing the Falcon through a meteor field.

This link should absolutely suffice. I searched my old hard drive and found this exact same archive of the soundtrack with all of the songs from the old Republic Commando website. After discovering the Tie Fighter soundtrack and its absence in the Windows 95/98 editions, I have a growing appreciation for Star Wars games with original soundtracks; they seem better suited for putting you in the right mindset as a pilot for the Imperial Navy or as a special forces clone commando than the theatrical John Williams score.

Sorry to resurrect a very old thread, but I recently purchased Republic Commando and it'd be great if GOG could offer the OST. Thanks!

It sounds great to me! Since it was originally a free download, I have mirrored it on archive.org. This way it can easily be both downloaded and streamed. (I also added lyrics tags and album art. Download the MP3s for that)
