One of the original resources I found when I started creating Burglars vs Brats was Cedric Neukirchen‘s Networking Compendium. Originally in a .PDF format, Cedric has updated it to now be part of his website.
This document breaks down and explains the somewhat confusing at first, but logically incredible Unreal Engine framework hierarchy & order of communication between key components.
A must-have, incredible resource for anyone embarking on a multiplayer game within Unreal.
