UNDERDEEP demo save transfer works automatically. The developer has confirmed that save data from the free Steam demo carries over to the full game, so you can try the dungeon crawler before buying it without having to abandon your earlier progress.
The demo arrived on 16 October 2026, followed by the commercial release later in the month. Both the demo announcement and the launch announcement specifically mention save transfer. There is no extra tool to download or manual file-copy process to follow.
Does UNDERDEEP demo save transfer happen automatically?
Yes. The developer says demo save data automatically carries into the full version. This was announced when the demo came out and repeated in its 30 October launch news.
It’s a useful feature if you’ve already explored several dungeon areas or spent time developing a character. You can continue with the paid version instead of deliberately starting a new adventure.
The studio’s UNDERDEEP demo save transfer announcement confirms the save itself, but does not list every individual item, map marker, stat or achievement. That matters if you are looking for an exact checklist of everything retained.
How to continue playing after the demo
Moving from the demo to the full game is straightforward. On the PC where you played the demo, open the official Steam listing, purchase and install UNDERDEEP using the same Steam account, and launch the full release. The developer describes the transfer as automatic.
There is no announced requirement to rename save files, browse Windows folders or use a third-party migration program. If you’ve been looking for a manual UNDERDEEP demo save transfer option, you shouldn’t need one for the normal demo-to-full-game move.
Make sure you’re on the correct listing. This guide covers UNDERDEEP, developed by UNDERDEEP and published by Hakony, with Steam app ID 4065440. Another title with a similar name has its own separate Steam page.
Does UNDERDEEP demo save transfer work between computers?
A save moving from the demo to the full version is not the same thing as moving that save from one computer to another. Steam Cloud isn’t listed among this game’s current Steam features, and the developer hasn’t promised cross-device syncing or account-to-account transfer.
If you played on a different PC, the studio’s UNDERDEEP demo save transfer statement doesn’t give enough information to guarantee that the save will appear there. Use the same PC and account for the straightforward route, or check the official Steam discussions for help with an unusual setup.
What progress will carry into UNDERDEEP?
UNDERDEEP revolves around a character you create, dungeon exploration, equipment and different jobs. You begin in the Newbie role and can later develop towards Warrior, Rogue, Ruler or Crafter. Exploring also fills in the dungeon map, and custom markers help you remember important spots.
Those systems explain why transferring a save makes a difference. But the developer’s announcement doesn’t itemise exactly which fields it copies. It confirms that demo saves carry over, rather than making a separate promise about every object or statistic.
For a look at the systems waiting for you after the demo, the UNDERDEEP beginner guide covers jobs, mapping, skills, idle exploration and karma.
When was UNDERDEEP released on Steam?
The Steam store lists 29 October 2026 as the release date. Its launch announcement was posted on 30 October, once again confirming that the demo save will work in the full version.
There is also an introductory 35% discount shown on the store until 12 November. Steam pricing varies by region, so check the amount displayed in your own currency rather than relying on a converted dollar figure.
If you are deciding whether to buy, UNDERDEEP demo save transfer is one less thing to worry about. The developer has confirmed automatic carry-over from the free demo, meaning you can play first and carry that saved adventure into the full Steam game.
