Epic Games, creators of the fantastic Unreal Engine, announced that they would be providing various Online Services to all developers, regardless of the engine they use.
This system would be known as Epic Online Services, provide back-end tools for ticketing and metrics, along with an SDK and a sample project to demonstrate the integration of their features.
You are free to use the Plugin in any way you like. Whether you want to integrate EOS into your project, use it as a starting point for your own Plugin, put it into a commercial project or something else? It is provided as is and any help we can offer, we do so through the Github or Forum pages.
Hopefully it will be of use to more people out there!
