Yes—existing full-game Steam saves are expected to remain usable after the free Complete Edition update. The announced 30 October 2026 patch upgrades the existing Steam game; it is not a separate purchase, and players should not delete their saves or start over just to receive the new content. However, the patch had not yet been independently confirmed working on players’ PCs when the latest save-specific information was published, so make a local backup before Steam updates.
What is happening to the Steam version?
On 27 October 2026, the official Volcano Princess account announced: “Volcano Princess will get a free Steam update on October 30! This free update will contain all the new content added for the multi-platform release.” Egg Hatcher, the developer, had previously told AUTOMATON WEST that the original PC game would be upgraded to include the Complete Edition content at no extra cost. This is an update to the existing Steam app, not a new Steam product owners must buy.
The official announcement gives the date, but not a release hour. A TapTap community recap reported a noon simultaneous rollout across Steam, TapPC, and mobile; the English official post did not confirm that time. Let Steam download the update when it becomes available in your client rather than relying on a specific hour.
Egg Hatcher put the intended save outcome plainly in its July 2026 interview with AUTOMATON WEST: “Yes, once the free update rolls out, the original Volcano Princess will be upgraded to include all of the Complete Edition’s content, so existing PC players will be able to enjoy every new feature from the Complete Edition at no additional cost.” The same interview said longtime players should be able to enjoy the latest version “without any hassle.”
Those are statements about the planned upgrade and expected compatibility, not a published save-migration test. As of the information available on 29 October, there was no English official patch note listing save compatibility, and no independently confirmed post-update results for every save slot, Steam Cloud copy, or Steam Deck installation. The reasonable expectation is that your existing full-game save carries forward—not that you must begin again—but a backup is prudent.
Do I need to start a new game?
No new game is required simply to receive the Complete Edition update. Existing Steam saves are expected to continue being used, although the available announcements do not establish whether every new feature will appear immediately in every in-progress save.
The update adds material to the original game rather than replacing it with a separate campaign. Egg Hatcher described Path of Two Shadows as a new dungeon for the daughter and one chosen companion, with more demanding combat, companion-specific scenarios, and unique illustrations. The broader Complete Edition package also includes extra story episodes, CGs, items and clothing, including a wedding dress; full Japanese voice acting; revised Japanese text; improved English localization; Traditional Chinese; a new opening movie; and revamped soundtrack and sound effects. The multi-platform release also includes Korean support.
Whether an existing save unlocks Path of Two Shadows immediately is a separate, unanswered question. English official materials do not specify if the dungeon becomes accessible during a particular year or month, whether an already-cleared playthrough receives a catch-up unlock, or whether starting another cycle is necessary. A TapTap recap suggests story-stuck players can begin a new cycle and ending-hunters can head toward the dungeon, but that is not a definitive mechanic specification. Do not erase a working save on the assumption that a new cycle is mandatory; wait for patch notes or an in-game unlock prompt.
How should I back up my Steam save before the update?
Copy the save folder somewhere outside the game’s save directory before Steam installs the patch. Egg Hatcher recommended manual backup before first launch during its February 2025 version 2.02 update, and the studio has previously described Windows cleanup of LocalLow data as a cause of save loss for some lapsed players.
- Open the save location on Windows. Press
Win+R, typeAppData, and press Enter. OpenLocalLow, then copyEggHatcherVolcanoPrincessto a safe location such as a separate folder outside AppData. The full path is typically%USERPROFILE%AppDataLocalLowEggHatcherVolcanoPrincess. - If using Steam Cloud, make the local copy before changing sync settings. Egg Hatcher’s 2025 guidance advised optionally disabling Steam Cloud while making a multi-device backup, then re-enabling it afterward. Keep the copied folder intact; a cloud copy is not a substitute for a backup you control.
- On Steam Deck, locate the game’s compatibility data. A community save-location reference places it under the Steam library’s
steamapps/compatdata/1669980directory. The exact nested path can depend on the Deck’s setup, so copy the Volcano Princess save folder you find there rather than moving or deleting compatibility data wholesale. - Let Steam update the existing game. Do not uninstall and reinstall as a migration method, and do not delete the save folder to “force” Complete Edition. The announced change is an update to the original app.
- Launch and check your save before removing the backup. If the save or slots do not appear, quit the game and check for the archive folder described below before creating a replacement save.
What if a save or slot is missing after updating?
First check the save directory for OldVersionArchives. In its 26 February 2025 Steam news for version 2.02, Egg Hatcher said old-version saves would automatically move there on first launch as a backup. The same post recommended making a manual copy before launching.
That earlier migration is useful context, but it is not proof that the Complete Edition patch will use the same process. Version 2.02 also increased the number of save slots to 24 and improved the save-file structure. Egg Hatcher later published version 2.02.02 on 19 March 2025 to fix a launch failure that could happen after Steam Cloud was enabled when old-save files were missing. The studio’s history is a reason to preserve a backup and check archives; it does not establish how many saves were affected or guarantee a particular recovery result now.
- Do not overwrite the old folder with a new empty save directory.
- Check
OldVersionArchivesand your separate backup before starting a new file. - Avoid Windows storage-cleanup tools targeting
AppDataLocalLow; the studio identified cleanup of that location as a cause of some earlier losses. - If the save remains unavailable, Egg Hatcher’s published 2025 support contact was
[email protected]. Include a copy of the packed save folder rather than sending your only copy.
The available announcements do not publish a Complete Edition save-load success rate or a guaranteed restoration procedure. Preserve all versions of the save folder until you have confirmed which one contains your progress.
Does this update apply to Switch, PlayStation, mobile, or Xbox?
The 30 October update is specifically the announced Steam upgrade. Nintendo Switch, PlayStation 5, iOS, and Android received Complete Edition on 30 July 2026, so saves created in those full-game versions already belong to the Complete Edition build. Xbox Series X|S had no Complete Edition update announced as of 27 October 2026.
| Copy | Complete Edition status | Is the 30 October Steam patch relevant? | What happens to a full-game save? | Can it transfer to another platform? |
|---|---|---|---|---|
| Steam PC | Original game released April 2023; Complete Edition content announced as a free in-place update | Yes; announced for 30 October 2026 | Expected to remain usable; back up first because post-patch results were not yet independently confirmed | No official cross-save transfer documented |
| Nintendo Switch, PS5, iOS, Android | Complete Edition launched 30 July 2026 | No; these versions already received the Complete Edition release | Remains on the platform where it was created | No official cross-save transfer documented |
| Xbox Series X|S | No Complete Edition update announced as of 27 October 2026 | No announcement for Xbox | Remains on the current Xbox build unless an update is announced | No official cross-save transfer documented |
| Volcano Princess Prologue demo | Separate demo, not the full game | No | Demo progress does not carry into the full release | Not applicable |
Nintendo eShop’s publisher notes are explicit about the demo: “Data played in "Volcano Princess Prologue" cannot be carried over to the full release. Thank you for your understanding.” That warning applies to the Prologue demo, including the Switch demo, not to an existing Steam full-game save. Gematsu also reported the no-transfer caveat for the demo.
There is no official documentation for moving a Steam save to Switch, PS5, mobile, or Xbox—or for moving a console or mobile save to Steam. Steam Cloud and Nintendo Switch Online Save Data Cloud are separate services, and no publisher-supported cross-platform conversion has been announced. Treat each platform’s save as its own until the developer says otherwise.
What new content should my existing save receive?
Egg Hatcher’s July interview and the Complete Edition overview republished by Gematsu describe the content planned for the multi-platform edition and, by the official October announcement, the Steam patch.
- Path of Two Shadows: a companion dungeon where the daughter brings one chosen companion. Egg Hatcher described tougher combat, sweeter companion-specific scenarios than the usual exploration events, and illustrations unique to the dungeon.
- More story and collectibles: additional episodes, newly written story material, CGs, items, and clothing, including a wedding dress.
- Voice and localization changes: full Japanese voice acting, with Mai Nakahara continuing as the daughter and Marina Inoue and Kento Ito joining the cast; retranslations of Japanese text, improved English localization, and Traditional Chinese. Korean support is also listed for the multi-platform edition.
- Presentation changes: a new opening movie, plus revamped sound effects and soundtrack.
The TapTap community recap also mentions interface, save-structure, and scene-presentation adjustments, and refers to a new romance ending and additional character-story material. Those points have not been stated in the English official Steam announcement, so treat them as community-reported details rather than confirmed patch-note specifications.
For scale, the Complete Edition is built on a game that the Nintendo eShop and Colorful Palette overview describe as having more than 50 endings. That does not mean every ending or new scene will be automatically marked complete in an old save; the available English announcements do not explain how existing completion flags interact with the additional content.
Frequently Asked Questions
What does save slot 0 mean in Volcano Princess?
The Miraheze Save Editing community wiki’s 10 July 2025 revision identifies slot 0 as the Auto Save. It also says the slot index is the final number in a save filename, which can help distinguish a missing manual slot from the automatic save.
Can Steam Cloud restore a save if my local copy is gone?
It may have another synchronized copy, but no Complete Edition announcement guarantees that Steam Cloud can restore a missing or conflicting save. Egg Hatcher’s 2025 version 2.02.02 notes describe an earlier launch issue involving Steam Cloud and missing old-save files, so first preserve any remaining local or archived files before attempting recovery.
Is the 30 October update definitely available at a particular hour?
The official English announcement confirms 30 October 2026 but gives no release time. A TapTap community recap reported noon, likely China local time, but that time was not confirmed in the English official post.
