Unity FPS multiplayer! What should I animate?

Hello guys. I spent a lot of time searching for the answer of my question but nothing.
So my question is : I want to make a FPS Multiplayer game. I use blender for animations.
What should i animate hands or the whole body?
My idea is that i should animate only hands with guns and Animate the body via Mecanim and then connect them together in Unity. Pls Pls pls help because im really stuck in this part. Thnx in advance !

Great question for the unity community, as this place is mostly for programming questions.

Here’s what I think:

  1. Skeleton should have two legs [jointed at knees], a spine, a head [for looking up-down], two arms [jointed at elbows], and five fingers per each hand [for holding gun].

  2. I like your idea. Mecanim the movement animations, so that the hands would be unique for each gun.
