There is exactly one special edition: the Harmony Edition, and it is physical only. It ships for PlayStation 5, Xbox Series X and Nintendo Switch 2 with the game on disc or cartridge, a premium box, a digital soundtrack, a double-sided poster with the map, and a 48-page softcover artbook called The Heart of Hela. Microids handles the retail release.
Everything else is the standard digital version, sold on Steam, the Epic Games Store, the Xbox PC app, the PlayStation Store and the Nintendo eShop. Xbox Series S and PC get no physical option at all.
The price question
No digital price has been announced on any storefront, and Steam is not taking pre-orders. The only numbers that exist are retailer listings for the boxed edition, and they move with local pricing rather than exchange rates: 39.99 euro in the eurozone, 149.99 złoty in Poland, 379 kronor in Sweden, 49.99 Canadian dollars in Canada, and 4,400 yen in Japan.
Languages are the same across every version: ten interface and subtitle tracks, with no full voice dub listed on any of them.
