Last updated
Death Mark keeps saves close to the classic PC pattern. A Death Mark folder in AppData holds .bin files, one per slot. No subfolders, no registry keys, no surprises.
Steam Cloud mirrors the same folder for hands off safety. Manual copies still win before reinstalls, since cloud restores lag the live files. The folder appears after the first save writes, so play past the opening chapter before hunting.
