All in the name of IMMERSION! Where does the player character keep all their weapons? If only it were possible to show weapons on your back with straps instead of floating and flat on your back, perhaps strapped to a backpack, and maybe, just maybe included with physics. That would be dope! And sadly, I dont think its possible to have a prone feature. A custom animation would need to be made for 3rd person. I will, however, pray for these features to come true. Maybe someday...
