Rockstar Games has today confirmed it is using NaturalMotion's euphoria technology in Grand Theft Auto IV.
The technology has been catching the attention of the games industry since E3 last year, when LucasArts started demonstrating its use of the dynamic character animation system in its upcoming Indiana Jones and Star Wars next-gen games.
Rockstar and NaturalMotion announced their partnership back in February and described their work as 'well advanced' - the latest trailer released by the controversial developer proved that was the case by demonstrating real time footage of the game in action using the technology.
GTA IV is built on Rockstar’s proprietary next-gen game engine, R.A.G.E. which the company says 'allowing for an unprecedented level of realism and interactivity'.
