The thing i see is not its usefullness now, but how the CODE and improvements may help aces high in the future.
Imagine spawning with a tommygun,or some german/jap weapon,and assaulting a town with some 250+ marines, and whatnot "AI"
Right now its just "finishing" something we always had, a pistol that never worked, so..at least it works now, altho its useless as all heck,but hey....its a pistol, not even a .30 cal machinegun or anything.
Some day,when we run our legs will move aswell. maby we will even have blood and death animations when being killed, vs the blowing up,part.
