Tanglewood with clear open-lobby status and Steam invitations.
How to join the host chooses Private Game and opens the lobby, then uses Invite to invite Steam friends. Friends accept the Steam invitation or use Join Friend in R.E.P.O. Everyone must play this same mashup version.
A remix of Haunted Haul 0.1.2 by ZekkiGaming, with the original MIT credit and notices preserved.
This version adds a co-op status bridge that survives R.E.P.O.'s scene transitions and shows whether a private or public multiplayer lobby is ready for friends.
Join through the game: the host chooses Private Game and opens the lobby, then uses Invite to invite Steam friends. Friends accept the Steam invitation or use Join Friend in R.E.P.O. Everyone must play this same mashup version.
Tanglewood, its ghost, cursed possessions and the local Phasmophobia importer are preserved. Each player needs R.E.P.O. and Phasmophobia; Melty installs BepInEx 5 and the mashup automatically.
Automatic Melty join links are not enabled because a second Steam account or PC was unavailable for a real host-and-join test. The test mode creates a native private Steam host on a debug save and verifies host readiness, Tanglewood and its active haunt.
