Machine Gun has a circular base and a trapezoid cannon.
Machine Gun's playstyle is very similar to Twin, as it is also used as a bullet spammer, although it has a single cannon with higher reload but with less accuracy. Just like the Twin, it does not put much of a fight with higher level tanks but it can defeat ramming tanks due to it's high reload.
Another similarity to the Twin is that, due to it's recoil, it can be used as a ramming tank.
