Compatibility notes
- Steam's current purchase is Heretic + Hexen. This entry covers original Heretic only, not Hexen or every included campaign; artwork and review totals describe the collection.
- Use APDoom 2.0 with original DOS HERETIC.WAD data. Its launcher detects supported Steam installations; remastered WAD support is not guaranteed.
- The core APWorld works with the stable client. Optional beta APWorlds add other features and should not be confused with the core options described here.
- Old guides still link unsupported APDoom 1.2.0. Install the current 64-bit build into a fresh directory and back up prior saves before migration.
- Optional death-reset puzzle logic and Pro tricks are intended for knowledgeable players. Increasing Check Sanity can substantially increase the amount of collection.
- Native Linux AppImage and Steam Deck support are explicitly documented alongside Windows. Support for arbitrary custom mods or same-map co-op is not established.
