I'm going to host a lobby of Serious Duke 3D, a remake of Duke Nukem 3D in Serious Sam 3 VR at 9PM EST Monday. 

Serious Sam 3 VR is 75% off and the Croteam VR bundle is an even better deal. Install Serious Sam Fusion. Get the mod by subscribing to https://steamcommunity.com/workshop/filedetails/?id=1432570016
