Rockstar Advanced Game Engine (RAGE) is a game engine developed by the RAGE Technology Group at the video game developer Rockstar San Diego with contributions by other Rockstar studios. Rockstar developed the engine to facilitate game development on Microsoft Windows, along with the PlayStation 3, Wii, and Xbox 360 consoles. RAGE evolved from the Angel Game Engine originally developed by Angel Studios for use in the sixth generation console era versions of the Midnight Club series and other Rockstar San Diego games.
