It was released under GPLv2 license by EIDOS on June 10th, 2008 (more info).
The names of the tracks were not known, so after they were open-sourced Steven Koenig decided to make up some names while he was preparing the audio files for inclusion in the source repository (Info.txt, sourceforge).
The PS1 demo track was re-discovered a year later and uploaded to the forums by user Sir Willis VvS.
I wanted to try & hit a balance between desolation & the idea of rising again from ground zero. It's pretty hard to keep it desolate & optimistic at the same time!
I have some songs that I wrote years ago that are just kicking about doing nothing that I would be honoured to have included in Warzone. I've played a few games whilst listening to them and they're not too intrusive and add a bit of atmosphere!
The tracks weren't named, so random names were made up with psi77's permission. So, my apologies for the pants track names!
