Everytime you kill an enemy, drop the weapon you killed them with and take theirs, using it until you kill the next enemy that will drop a weapon- repeat the process.

Fun?

Well then take it's claws!

Throw the Claws at people? Gotcha. What about a nvde person what then?

Umm, it depends on the gender. Edit: Use their limbs.
