Those things in arms are blades, very useful to dismember cyborgs greater than she.
Their root is extracted from forearms, next are forged in air, so its needed some shapekeys, material animation and work of composition.
Later I'll improve arms, they have more muscles.

Thanks Reddog9, I have rigged and weightpainted another makehuman character, and I like results. My rig is conventional, and it is interesting get a rig valid for any character. Email me your one, I will test it and try to add some feature.
