Best weapon for fighting minibosses

The best weapon to use for fighting mini-bosses in 1 player mode is the Judacator.
It is very accurate, shoots fast, and you can charge a shot to shoot 6 at a time.

On top of that, it takes away a hefty amount of health from your oppenent too.
So, if all else fails during a mini-boss fight, use the judicator

(P.S. Shooting the enemy in the head will take away even more damage)
