Horizon Zero Dawn keeps the working save set in Documents. Before New Game+ preparation, modding, or migration, preserve the entire Saved Game directory rather than only the most recent checkpoint.
Identify the exact save you intend to edit
The researched Horizon Zero Dawn Complete Edition PC save location is Windows: %USERPROFILE%DocumentsHorizon Zero DawnSaved Game. Known file/folder pattern: manual/autosave checkpoint folders and profile records. Storefront context: Steam, Epic Games Store, GOG. The active Steam, Epic Games Store, GOG installation determines which local profile and cloud copy can overwrite the save. Identify the storefront and account before restoring files. Do not edit a similarly named file from a different profile, edition, or cloud cache.
Make an untouched backup first
Close Horizon Zero Dawn Complete Edition, let the launcher finish any synchronization, then copy the complete documented save directory to a dated folder outside the live path. Preserve companion files rather than selecting only the newest-looking record. Keep that copy outside the live save directory and do not overwrite it with later experiments. Cloud context: Cloud support is storefront-specific; manual backups should be taken after synchronization completes. If a launcher can synchronize the save, prevent it from silently replacing either the original or edited copy while testing.
Understand the format boundary
Horizon Zero Dawn groups checkpoints in a Saved Game directory. Preserve the full directory so slot/checkpoint metadata remains aligned. File-extension context: No single extension is sufficient to identify every relevant save record. Compatibility note: Treat saves as version-, storefront-, account-, and mod-sensitive unless the game or a separately verified migration workflow proves otherwise. A similar filename or extension is not evidence that two releases are interchangeable. These facts help identify the save but do not automatically reveal every field, checksum, encryption rule, or version-specific structure inside it.
Use only a Tool whose claim matches the file
Generic viewers and diff tools can inspect bytes without claiming game-specific semantics. A game-specific editor should be used only when its Tool page explicitly lists Horizon Zero Dawn Complete Edition, a matching supported version/container, and a Verified operational runtime. A planned URL or Game Hub is not evidence that an editor exists.
Test the edited copy safely
Write to a new output file when the Tool supports it, keep the original backup, restore the edited copy into the correct profile/storefront location, and launch the game only after the file operation finishes. If the game rejects it, If progress is missing after a restore, confirm the active Windows account, storefront/profile, cloud state, and exact directory first. Restore the untouched backup before experimenting with individual files or older autosaves. Return to the untouched backup before trying another change.
Verification context: Windows save location, file-boundary, launcher/cloud, and backup notes were reviewed against the linked game-specific references for Horizon Zero Dawn Complete Edition. This Game Hub is documentation only and does not claim a new game-specific Save Editor.
Recorded Phase 40 evidence boundary
This Phase 40 entry is grounded in the researched PC save boundary for Horizon Zero Dawn Complete Edition: Windows: %USERPROFILE%DocumentsHorizon Zero DawnSaved Game The recorded file or folder pattern is manual/autosave checkpoint folders and profile records. These concrete identifiers are retained so backup, transfer, recovery, and editing preparation remain tied to the documented game/storefront context instead of a generic extension guess.
