Modder ‘sfb’ has released an AI-enhanced HD Texture Pack for Severance: Blade of Darkness, called Blade of Darkness Reforged. Alongside new detailed textures, this mod also improved the textures of all characters.
Blade of Darkness Reforged aims to update the visual fidelity of Blade of Darkness whilst not straying too far from the original look and feel. Furthermore, this mod also packs some minor gameplay enhancements.
As the modder noted, each and every texture is based on an upscaled version of the original allowing for greater visual authenticity and feel.
