How to install and play Serious Duke 3D. Serious Duke 3D is a remake (and reimagining) of the first episode of Duke Nukem 3D, and it is mod for Serious Sam Fusion 2017. Serious Sam Fusion 2017 itself is only a engine and when you have Serious Sam 3 or Serious Sam HD they will appear as DLC content for Serious Sam Fusion 2017. Simple, huh? 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 assetts and music tracks made exclusively for this mod.
