Rockstar North's Grand Theft Auto IV (PS3, X360) is the first retail game to feature NaturalMotion's euphoria animation technology.
In advance of the title's release, NaturalMotion sent over a video demonstrating how the real-time animations of the euphoria engine differ from other solutions, such as ragdoll physics.
The euphoria technology is also being utilized the physics-intensive PlayStation 3 and Xbox 360 editions of LucasArt's Star Wars: The Force Unleashed as well as NaturalMotion's own football game Backbreaker (PS3, X360).
