This is an example integration of Unity’s UNET HLAPI and Steamworks P2P networking using Steamworks.NET.
I built this as a proof of concept to confirm that Rival Megagun could have online multiplayer features on PC without any extra costs. I wrote about it and open sourced it for other Unity developers to use as a starting point.
Released October 2017.
