When the PlayEveryWare EOS Unity plugin is present, the SDK now: - Calls Identify() with the logged-in EpicAccountId automatically at Init - Sets distribution_platform = "epic" in game_launch properties when the game was launched from the Epic Games Store Detection uses C# reflection so there is no hard compile-time dependency; games without EOS are completely unaffected. Both EOS Unity plugin install methods are supported: - UPM package (com.playeveryware.eos / com.Epic.OnlineServices assembly) - Legacy DLL install (EOSSDK / PlayEveryWare.EpicOnlineServices assembly) EGS detection is based on launcher-injected CLI args (-EpicPortal, -epicapp=, -epicenv=), not EOS initialisation, so Steam-only games that use EOS for cross-play are not misattributed. link.xml: type-level preserve="all" entries for AuthInterface and EpicAccountId prevent IL2CPP High stripping from removing the method metadata that reflection depends on. Assembly-level preserve="all" only protects type declarations, not method bodies or their metadata. examples/audience/Assets/link.xml mirrors the same rules because Unity's linker skips package link.xml when the package is a file: path (dev mode).
