Ronin

To make The Force Unleashed as realistic as possible, LucasArts created a new engine code-named Ronin. But while the majority of its technology is proprietary, LucasArts had no hesitation about licensing third-party technology. It acquired Havok's physics engines; NaturalMotion's Euphoria for realistic, AI-driven character animations and Pixelux's Digital Molecular Matter (DMM), for spectacularly destructible environments.
