Source catalog Release APDoom client v2.0.0 · Archipelago core World 0.6.7Core World source: Archipelago 0.6.7 · client release: APDoom v2.0.0Show technical details

Archipelago 0.6.7 defines 474 unique addressable location entries across all four episodes. The default episode toggles select Episodes 1–3 and leave Episode 4 off, giving 348 checks: 27 level exits and 321 ordinary randomized item slots. Each enabled exit receives its matching fixed “- Complete” event and is removed from the random item-pool size. Nine explicitly one-attempt checks stay active but cannot hold progression items unless Allow Death Logic is enabled. These counts come from the pinned source tables and generation code; no seed or DOOM session was run.

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

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

Playing with others

A solo DOOM campaign per slot participates in live or asynchronous multiworld play. This does not promise native same-map co-op support.

Known scope and limitations

Buy/install Steam's DOOM + DOOM II collection; this entry covers original DOOM, not every campaign included in that collection. Artwork and review totals refer to the collection.
Use current APDoom 2.0, not legacy 1.2.0 still linked by older tutorials. The maintainer explicitly withdraws support for the legacy client and documents serious old DeathLink issues.
The new launcher detects installed Steam WADs. If copying manually, use the original DOS DOOM.WAD from dos/base, not a rerelease or shareware WAD.
Install 2.0 in a fresh folder rather than mixing its 64-bit DLLs with the older 32-bit package. Back up your existing saves separately.
The stable client works with the core Archipelago world. Separate beta APWorlds add features but are optional; this overview describes core gameplay.
Windows and Linux AppImage builds are published, with explicit Steam Deck support. Custom WADs and additional sound modifications have their own compatibility limits; they are not automatically supported by this entry.
