# GTA4Unity: reconstructing the GTA IV world in Unity

> GTA4Unity reconstructs GTA IV world loading and rendering in Unity 6 using the player's original game files. It parses IMG archives, WDR/WFT models, WTD textures, IDE definitions and IPL/WPL placements, converts RAGE coordinates to Unity space and streams world geometry through Unity's Entity Component System.
