Atomic Heart PC save structures vary depending on whether you play via Steam or the Xbox App / PC Game Pass version. Steam stores save files as `.sav` formats within your hidden `LocalAppData` system folder under `AtomicHeart\Saved\SaveGames\`. PC Game Pass utilizes Microsoft's `wgs` container folder system inside the `Packages` directory. Direct file swaps between Steam and Game Pass are incompatible without re-naming binary save headers via save editor scripts. Standard patch updates maintain file structure integrity without corrupting old save slots. Steam Cloud or Xbox cloud save features automatically overwrite manually modified save slots on boot if left active. Disabling cloud sync features in your launcher settings before dropping in replacement save files prevents file rollbacks.
How to Apply This Save File Correctly
Essential Save File FAQs
Does this save file work on both Steam and PC Game Pass builds?
Steam uses standard `.sav` files in `LocalAppData`, while Game Pass uses `wgs` container folders. You must convert save structures between formats.
Why is the downloaded save slot not appearing in the main menu?
Cloud synchronization likely replaced your copied file on launch. Turn off cloud saves in launcher options, re-paste the save, and boot.
Are all polymer glove upgrades, weapons, and testing ground polygons cleared?
Yes, every polymer skill branch is maxed, all weapon craft recipes are unlocked, and all Testing Grounds sit at 100% completion.
Will using a completed save file trigger anti-cheat bans or break active mods?
No, replacing single-player save data carries zero anti-cheat checks and works alongside visual and performance mods.
Can I explore Facility 3826 in free-roam mode using this save file?
Yes, select the completed save slot from the main menu to access open-world free roam across Facility 3826 with maxed stats.
Preventing Progress Loss: Backup Reminders
Copy your personal `<YourSteamID>` folder to your desktop before modifying any save files. If the replacement save fails to load or appears corrupted, restore your desktop backup. Cloud sync services will overwrite local edits if left active, so disable cloud save options in launcher properties before swapping data. Replacing single-player save data carries zero ban risk. Custom visual reshades or blueprint tweaks function smoothly alongside completed save files.
Summary
Loading a 100% completion save gives you max polymer glove upgrades, all unlocked weapons, completed testing ground polygons, and full collectible sets. It removes the necessity of repeating puzzle chambers while keeping all combat gear fully stocked for immediate exploration. Make sure launcher cloud sync remains off during file operations, and place replacement files into your unique Steam ID subfolder inside `LocalAppData`. Always copy your original save folder to your desktop before making changes. Open your `LocalAppData` directory right now to back up your original saves before installing.
