Question about Havok

I was looking at the site for the engine and I noticed one of the features of the Havok Engine is this:

-New, localized ragdoll effects (for example, you can get a dead arm if you get shot in the shoulder) and bone level blending of key-framed animation with physics.

Has any game used this feature? I always wanted a physical affect to happen when you shoot aguy in a certain limb (Shoot a leg and he' ll drop down but still be able to shoot, or like the example from the site shoot the arm and it becomes useless but the enemy doesnt suddenly kill over.)
