Back in February 2020, NCSOFT started the Frontier World server for Blade & Soul. This server is specially made with the upgraded version, Blade & Soul Complete, using Unreal Engine 4 with several enhanced features. However, things have not been rosy since then, and NCSOFT admitted yesterday that despite efforts to make the Frontier World version to be more enjoyable, they were unable to show “satisfactory results.”
UPDATE: Blade & Soul – NCSOFT announces new Unreal Engine 4 upgrade set for June launch
As such, the Frontier World server is sunsetting on 6 May 2021, with the refund process now ongoing. It seems that the project to upgrade Blade & Soul from Unreal Engine 3 to Unreal Engine 4 is officially dead, as NCSOFT also teased that “a new beginning” for Blade & Soul arrives this June, where the game will “go one step further.” Stay tuned for more updates in the coming hours!
