hey you know how in the start of the campaign of halo combat evolved how master chief doesnt have a weapon on him, i was wondering that if you can make it possible when maste rchief is not holding a weapon but can still melee, for example the left button of the mouse makes and master chief melee with his left arm and the right button makes master chief melee with his right hand and then the regular melee button makes master chief melee with both his hands. but then when he walks over a grenade how will that work?

thx man!!!!
