# HK: Dual Souls: an AYN Thor port of Hollow Knight

> HK: Dual Souls ports Hollow Knight v1.5.12620 to the AYN Thor Android handheld through a same-version Unity rebuild from the user's GOG or Steam copy. Its runtime adds a second-screen HUD, map, inventory and charms, while patch tooling prepares game data on the device. Some shaders are reconstructed approximations.
