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.

Requirements
Serious Sam 3
for playing in VR, Serious Sam 3 VR edition is needed.
1,3 GB space

VR support
The mod should be fully playable in VR. There are, however, a couple of bugs and general clunkyness with the VR support atm (cutscenes in particular).
Also note that smooth locomotion is required for the most part.

MP/Coop
Besides SS Fusion being unstable with custom maps/gametitles, the maps in this mod were designed for singleplayer gameplay, It's likely that you run into issues when playing online. I'll try to improve the online functionality as much as I can in future updates
