Our good friend Lance (Ransu90) took up a project over the six months to produce a re-mastered musical score in time for the DOOM 20th anniversary. Releasing some tracks prior to the 20th anniversary of DOOM, lance has received a wide range of feedback which has helped him improve the re-mastered tracks.
The original plan being to just re-master Doom, Doom II and Final Doom TNT: Evilution, adding Hexen and Heretic as they also ran on Doom’s engine at the time. With the possibility of Duke Nukem 3D’s music also being added to the list which would be a collaboration between Lance and Neurological.
