Probably not, because your asking about 3rd party tools. The thing is that what your looking for is already in Unreal.
Gore is a combo of 3D meshes, particles and decals; all of these are in engine. You will have to learn how to use these to make your gore.
Finding a already made core combo system is going to be real hard, you will have to hope there is some talented artist who got together and made one.
My advice is this: Learn particles and decals, it's the easy part.

Forget about realistic AI reaction and settle for something simple. Killing Floor 2 spend a huge amount on motion capture.
