Might have found a new (?) code name in UE4, but no clue what it could be: Erebus (The god of darkness in Greek mythology) There is also the abbreviation "TST2" used for this platform: Path: C:\Program Files\Epic Games\UE_4.20\Engine\Plugins\Online\OnlineSubsystem\Source\Public\OnlineSubsystemNames.h And here the name is used side by side with PS4 and Xbox: Path: C:\Program Files\Epic Games\UE_4.20\Engine\Plugins\Online\OnlineSubsystemUtils\Source\OnlineSubsystemUtils\Private\PartyBeaconState.cpp Unfortunately, those are the only references I have found. Has someone heard this name before? Maybe it's just something boring, but who knows, lol. EDIT: In the second pic, it also says "bPS4SeenOtherConsole", maybe that hints at it being a console?
