One thing that separates the two halves of Final Doom is that TeamTNT composed many original tracks for Evilution, and I think that this added greatly to its originality and charm, even if some of the MIDIs were really short and/or just not that great. So, what if Dario and Milo Casali were musicians themselves, or what if they had other musicians - perhaps even TNT's music team, or even Bobby Prince himself - on board with the project to provide an original soundtrack to the maps of the Plutonia Experiment?
This project is the Doomworld community's answer to that.
Every one of you who contributed. Great work, everyone! :D
