In case some of you never played the game back in the day on the Amiga, you can hear the difference in audio quality here... it's a pretty big difference -
PC version
Amiga version

I don't think anyone disagrees that the Amiga version is far superior to the PC version, especially in the sound department. It's even more noticable with the intro music though.
Amiga version
PC version (for some reason, only the HQ version works)
It ain't really Cannon Fodder without "War's never been so much fun".

As noted on the YouTube page, that intro version is not 'the PC version' you have to remember how limited the emulation options of DOSBox actually are, especially with regards to sound. I played it originally, on my PC (under Win9x actually) and the music was close enough to the Amiga quality as to require side-by-side comparison in order to show that the Amiga was better (which it was).

The intro song is disappointingly not the classic Amiga version though. :(

I just installed it and was shocked how bad the sound is. I would like to know if its the fault of DosBox environment or if the difference to the Amiga version really is this massive.
Knowing the Amiga version from back in the days, this is unplayable for me ;) :(

It got nothing to do with DOSBox emulation.

The Amiga version used the MOD file format for sound, which uses bits of digital sound samples, where the PC version uses synthesizer sounds.
Digital audio didn't became widely possible on PC before Soundblaster became de facto, and even then most games still insisted on using synthesizer sounds for music until the CDROM era.

This is why Amiga versions pretty much always sound better than the PC version.

Actually, if you emulate the Roland MT-32 chip, you get this:

I found a way to get the sound from the amiga in the PC version. There is a demo version (from march 1994) of the PC game with sound like in amiga. This version has an installl.exe file in which you can select soudblaster as a source of music. I copied install.exe file to the folder with the full version of the game. I set the sound blaster as a music source.
I was shocked when the full version game has started with the sound like on amiga!
You can find this demo on "Supergames 4" shareware cd. Search it on archive(dot)org

The game after changes runs a little slower (black screen for 10 seconds. during startup).

Anybody managed to hack it so it plays the amiga sound / music instead...
