Ludwig animation

I have bein using blender 3d for quite a while now and im trying to set up a ludwig/matrix fight scene,just wanted to find out how to import muiltiple ludwigs into the scene because i mange to get them in but i cant use ludwigs face cubes?someone plz help?

Edit:You could just Append The matrix scene in to the Ludwig scene. File/Append/(Find Matrix Scene Blend)/Object/(Find of the objects you want to use.)
Then just Duplicate Ludwig and his bones.

or, when you import from the ludwig scene, right click all the objects you want to import (ludwig mesh, armature, custom bone shapes, ect) before you click import. that way they all stay linked together.
