You can do runs on your own save file, but if you want a maxed save, they are available here (Google Drive link) or in the Resources tab.

Save File Information

Save files are stored in varying places depending on the platform.

Windows:

C:\Users\<Your Username>\Saved Games\Hades II

Steam Deck:

/home/.local/share/Steam/steamapps/compatdata/1145350/pfx/drive_c/users/steamuser/Saved Games/Hades II/

MacOS:

/Users/<Your Username>/Library/Application Support/Supergiant Games/Hades II

Loading A Save

1. Choose which profile you want to load the save into (profiles are numbered 1-4 based on the “slot” on the title screen)
2. Optional: If the profile is empty, copy the Profile1.ctrls to ProfileX.ctrls, X is the new slot. Do the same with Profile1.sjson to ProfileX.sjon. If your main file is not the first slot, use the file you normally use instead. This should prevent you from having to rebind controls and set up display settings (but you can also just do this in game)
3. Download the save you want to use, move it to the correct location, and rename it to ProfileX.sav (where X is again the slot you've selected)
