Trying to import model from blender to unity, rig is all messed up when it arrives in Unity

So I'm trying to import t$$anonymous$$s model from Blender to Unity, right?

It has an armature/rig, animations, a mesh and material.

However once it arrives in Unity it looks like the following, and all of the animations are messed up as well with the arms all messed up.

I dont' really know what to do, I've been hacking at t$$anonymous$$s for like 2 solid days.
