GAME MECHANICS

Explore game mechanics

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

Source catalog Release Engine 2.2.3 / APWorld 2.6.0 / Plugin 1.5.4APWorld 2.6.0

These 1,997 entries are checks that current options can generate across configurations, not one seed. The World reserves 1,000 shop and 1,000 star IDs, while its current pool formula reaches at most 858 shop checks or 429 stars. Defaults derive 174 checks: 89 missions, 30 shop purchases, 25 cargo ruins and 30 stars. Two vehicles are precollected; the remaining 97 vehicle licenses, 10 traps, 47 utilities and 20 speed boosts fill the default item pool. Mission tasks and shop stock vary by seed. The bundled setup guide says monthly profit, but the v2.2.3 World source defines yearly net profit over the last four completed quarters. No generated seed or game session was tested.

Playing with others

Each player runs a separate company in a separate local game connected to the Archipelago room. Optional DeathLink sends vehicle crashes to the multiworld and is off by default. This is not support for several companies sharing one networked OpenTTD game; keep the external client connected for exchanges.

Known scope and limitations

  • OpenTTD is available on Steam, but this integration runs a separately distributed fork based on OpenTTD 15.2. Installing the ordinary Steam build alone does not install Archipelago support.
  • The maintained route requires Solida's separate Multiworld Launcher on Windows 10 or 11. Add the downloaded .londonplugin, then install the game package through that launcher. It is not a Panludia launcher integration.
  • Use engine 2.2.3, APWorld 2.6.0 and plugin 1.5.4 from the release. The plugin manifest requires Multiworld Launcher 3.22.5 or later; the README's older 3.21.2 minimum is not sufficient evidence for this plugin.
  • Connect through the launcher and use Join AP in the game. There is no standalone server-login form in the maintained game build. The attached legacy 1.4.1 package has a different connection system and is discontinued.
  • Native networked or multi-company play is not supported: the known-bugs document identifies state differences that can desynchronize clients. The exposed Multiplayer Mode option does not establish that those remaining issues are fixed.
  • Prefer a modest map, normal or easier targets, vanilla content and conservative options for a first session. A 4096-by-4096 map can require gigabytes of memory, minutes of generation and noticeable pauses with Wrath enabled.
  • The README's five goals and monthly-profit wording are outdated. Current profit targets use the last four completed quarters. Existing seeds keep several baked targets; install the current world when generating a new campaign.
  • The generator's shop-access rule checks cargo capability, not the game's full mission-credit gate. The latest engine reduces that gate's cost, but timing estimates and extreme option combinations should not be treated as exact logical guarantees.
  • Install required NewGRFs before starting and restart after adding them. Some sets do not support Toyland. The maintainer also reports menu-scanning and unavailable OneDrive Documents-path problems that can block content activation.
  • The launcher is distributed unsigned and plugins execute code with its permissions. Review the source and plugin declaration; a displayed hash or consent dialog is not a security certification.
  • Only the documented Windows integration route is listed. The native Steam game's Linux, macOS and multiplayer support does not prove those capabilities for this fork. No independent full Panludia campaign is claimed.

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