>>8279951Weapon integration isn't really partsforming in my book since it has specific engineering to make it fir in and can allow for additional configurations like you have done. I usually like it better than having a weapon that's just a weapon you plug into an available port when it's in altmode.
Ten again, I do enjoy when a weapon actually looks like it belongs plomped onto a vehicle like a functional turret, so honestly it just depends.
Point is no, Impactor is not a partsformer.
