Playing with others

Each player runs a separate save and Archipelago slot. Rolling up tracked objects sends the assigned multiworld rewards; incoming items unlock levels, characters or cosmetics, add Planets, or queue consumables and traps. Optional DeathLink shares failed stages.

Known scope and limitations

  • Use the matching v0.3.0 APWorld and plugin. The World requires Archipelago 0.6.7; the client advertises protocol version 0.6.6. The documented loader is BepInEx 6 IL2CPP build 783. Unix support is described through Wine/Proton, without an independent runtime test here.
  • A catalogue entry is not a promise of inclusion: level exclusions, Skip Tutorial, collection mode and milestone settings change checks. The collection modes are mutually exclusive. Forced local Stardust checks cannot hold progression.
  • When clear Planets are enabled, the percentage-goal denominator adds non-starting level unlocks rather than all fixed Planet checks. With defaults this computes 73 required from a modeled 122, although 128 Planets are placed across the pool and clear checks.
  • Limited reward space reduces requested pool Planets first and can then omit cousin/present cosmetics. Starting levels and the starting cousin are randomly selected.
  • The native client has no reconnect path without restarting the game. Keep Easy Finale on and start a fresh save. Displayed level positions can be displaced; the maintainer documents selecting their intended location or reloading the scene. No full playthrough or native rebuild was performed.
