Sunkenland stores its save files at %USERPROFILE%\AppData\LocalLow\Vector3 Studio\Sunkenland on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps every version, so a corrupted or overwritten save is one click from restored.
Where Sunkenland saves are stored
- Windows —
%USERPROFILE%\AppData\LocalLow\Vector3 Studio\Sunkenland
How to open the save folder
- Windows — press Win+R, paste
%USERPROFILE%\AppData\LocalLow\Vector3 Studio\Sunkenland, and press Enter (the AppData folder is hidden in Explorer, which is why this path is so easy to miss — pasting it skips the hunt).
Backing up Sunkenland saves automatically
- Install Checkpoint64 (free) and pick Sunkenland — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
Sharing Sunkenland saves with friends
Sunkenland has co-op, so the folder above usually lives on one person's PC — whoever hosts. When they're offline nobody else can carry on, and if two people play separately, one session quietly overwrites the other.
Checkpoint64 lets a small group pass one Sunkenland world around instead of renting a dedicated server. Whoever plays next takes a server-enforced lock, pulls the latest save, plays, and pushes it back; everyone else stays read-only until the lock frees up, so nobody saves over anybody. Every version is kept, so a bad session is one restore away. The dedicated server alternative guide walks through the full take-turns flow.
