Serious Duke 3D is a reimagining of the first episode of Duke Nukem 3D. While the main idea is to recreate the classic Duke 3D experience, some modern elements are added to the mix, such as redesigned and expanded level areas, occasional enemy waves/arena fights and new weapons. Also features redesigned enemy and weapon models from DNF with custom animations, as well as a selection of sounds and voice taken from several official Duke games and beyond that lots of custom assets and music tracks made exclusively for this mod. The mod supports virtual reality gameplay if it is installed with the VR edition of Serious Sam 3.
