Steamworks plugin for Unreal Engine for those who wants a full steam integration and has no plans to deploy anywhere else. PC games are different and is worth to lift the contrainsts that consoles and mobile platform has put into the OnlineSubsystem abstraction layer.
This plugin does some basic plumbing and exposes several classes for C++ and blueprint usage
if you only need a simple peer to peer multiplayer, the default OnlineSystemSteam is enough
This is not an OnlineSubsystem implementation
