The studio confirmed that progress made in the demo can be transferred into the full game, which is scheduled to launch on October 15, 2026.
Background
Castlevania: Belmont's Curse marks Konami's latest entry in the long-running Castlevania franchise, which the company has overseen since the series' debut in 1986.
The new title arrives on Nintendo Switch, continuing a platform history in which many modern and classic Castlevania titles have appeared on Nintendo hardware.
Demo details and save carryover
Konami has stated that the demo will let players experience the "early stages" of Belmont's Curse.
In journalistic terms, Konami confirmed a demo offering an early-stage slice of the game will release on October 1, 2026, and any save data created in that demo can be carried over to the retail release on October 15, 2026.
This carryover ensures that time invested in the demo will be preserved in the full product.
Technical specs and install requirements
Konami's official information for the Nintendo Switch version specifies that the game runs at 30 frames per second on that platform and requires a minimum of 3GB of storage space to install.
Players planning to download the demo or full title on Switch should ensure they have adequate free space on their console.
Distribution and availability
The demo will be available for Nintendo Switch users to download on October 1, 2026.
Demos on the Switch platform are typically distributed through Nintendo's digital storefront, the Nintendo eShop.
The full game is slated for release on October 15, 2026.
Why it matters
Allowing save transfer from a demo to the full release removes a common friction point for players who want to preview gameplay without losing progress.
For fans of the franchise and Switch owners, the demo provides a chance to evaluate Belmont's Curse ahead of its mid-October launch while preserving any progress made.
