# OpenUG2: a Need for Speed: Underground 2 engine reimplementation

> OpenUG2 reimplements the Need for Speed: Underground 2 engine as a native racing prototype that reads the player's original game data. It parses STREAM*.BUN scenery, GEOMETRY.BIN car geometry and TEXTURES.BIN textures, then renders drivable circuits with AI opponents, laps and standings.
