Unreal Online Subsystem (OSS / OSSv2)

The Online Subsystem is Unreal's abstraction over platform online backends (Steam, PlayStation, Xbox Live, Nintendo, EOS, Google Play, Apple GameCenter, Discord). It exposes a consistent C++ interface for identity, sessions, friends, presence, achievements, leaderboards, voice, store, and entitlements that maps onto platform-specific or EOS-backed implementations.
