DOOM 1993Archipelago randomizer mod

Compatibility notes

• 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.
