Throwing knifes, needles, and axes!!

I would just like to say that throwing knifes and the others named above would be awesome to have in the game. Just sayin, and if a ninja costume could be included for ghost mode that would be cool too. The knifes would be lighter that the ones you carry around now, but would fly through the air with the same gravity of a grenade and do moderate damage. Throwing axes would be heavier and would not go as far, but would do great damage. Needles would be extremely light, as if there were no weapon, and would fly through the air straight ahead with a little down-force so they decline slowly, but would do little damage.
