Travel through adventure fields, unlock six playable characters and clear stages, bosses or optional side activities to send rewards across a multiworld. Area gates use emblem counts or shuffled keys; the final goal is Perfect Chaos.
1,680 optional reward checks; 80 are enabled by default. Up to 1,676 coexist because unified bosses and the shared Twinkle Circuit check replace their separate alternatives. The fixed Perfect Chaos completion check is described under Goals.

Playing with others
Each player uses a separate SADX save attached to one Archipelago slot. Reward checks exchange items with other slots. Optional DeathLink shares deaths, RingLink shares ring changes and TrapLink relays traps; these do not create shared in-game co-op.
Known scope and limitations
Use the 2004 PC game setup and the release-matched SADX Mod Loader package. The packaged APWorld reports 1.2.2 and requires Archipelago 0.6.3 or later; the release tag is v1.2.2b.
S-rank missions require Hard logic or above. Extended stage/boss entrance shuffling disables special Chao egg checks. Requirements can automatically enable their related checks during generation.
The mod expects completed stage, mission and boss counters for its final gate, while the World models their reachability. These are distinct checks; the final fight must still be won.
The distributed World and pinned sources were inspected, including the client coordinate tables. The DLL was not rebuilt or run; Windows, Proton and completed multiworld behavior were not tested.
