Aside from the PlayStation 3 gaming community, it looks like another group's very happy with the way Ninja Theory's Heavenly Sword is turning out. Middleware company Havok is apparently all praises for the title, which used the company's physics Software Development Kit (SDK), and animation system. Given the way Havok CEO David O’Meara phrased his company's official remark, it looks like they're happy about the same stuff we're enjoying for the game:

Heavenly Sword is a fantastic game on a number of fronts. An emotionally rendering storyline, a beautiful heroine, a wide range of villains, epic scale destruction, in a beautiful environment, with the realism of Hollywood visuals offers the player an incredible gaming experience, especially on PlayStation 3.

Havok Complete allowed us to enhance game-play in Heavenly Sword by enabling us to create characters that responded to a complex physical world, with a rich set of physical interactions. The characters respond in a convincing way to physical forces they experience, such as getting back up in a realistic manner when they have fallen down or negotiating obstacles they encounter.
