Guys, why are you suddenly arguing about little details on the model(s), their purpose and the realism and functionality of these made-up, futuristic or maybe not... something... weapons? Why does it suddenly matter how a guided-plasma-rocket-minigun of the size of a pistol with a photon-torcreep-assault rifle with underbarrel nuke-launcher attached to it works?

To the modeling-style-argument:
If Takato wants to model like this then let him. If you suggest a different style to him, okay. And if he says no, accept it.
