GAME MECHANICS

Explore game mechanics

Browse possible checks, rewards and settings. What appears in your game depends on your World options.

Source catalog Release ATLYSS Archipelago v0.2.2 paired APWorld and BepInEx DLLRelease tag v0.2.2; APWorld archipelago.json reports world_version 0.2.0

The 86 default checks are distinct network locations; the mechanics list contains 168 candidates across all goals and toggles. Two tool checks are active by default but carry their tool as a fixed local item, so they do not add a randomized pool slot. The release tag and internal APWorld version differ (v0.2.2 vs 0.2.0).

Actions and milestones that can send a check to your multiworld.

168 locationsDefault marks checks from configurations selected by standard options; the generated set can still vary with logic and seed.

Playing with others

Archipelago exchanges rewards across player slots. The maintainer describes one slot per game instance and shared benefits within that instance; separate slots require separate instances or a host handoff. Native co-op details should be confirmed with the author before planning a shared run.

Known scope and limitations

  • This is an actively developed preview, not a stable release. Use the APWorld and game DLL from the same GitHub release with Archipelago 0.6.7 or later.
  • Release 0.2.2 still declares world version 0.2.0 internally. Thunderstore uses a separate package number, 0.2.4; do not infer compatibility from the displayed numbers alone.
  • Install BepInEx 5.4 and the plugin, or use the maintainer's r2modman profile instructions. The mod manager does not install the APWorld into Archipelago for you.
  • Enter room details in Settings > Archipelago, then create or load a character before pressing F5. The connection cannot start from the main menu without a loaded save.
  • Use a separate character and keep backups for each run. Resending saved milestones after reconnect is documented, but complete offline delivery and all co-op combinations are not independently verified.
  • Shop checks are not immediately available at the start: the current release gates them behind the normal Catacombs portal progression. More XP does not replace required portal or equipment items.
  • DeathLink is described as a client setting, but the released APWorld options do not expose a DeathLink field. Do not assume that a YAML toggle alone enables it.
  • Only the Windows Steam setup is established here. A general mod-manager reference to Linux is not proof that this integration works under Proton.

This integration is maintained independently of Panludia. Downloads are provided by its maintainer. Contact the maintainer through the linked repository or support channels.
