How to defeat Katagawa Ball; mainly use corrosive damage to deplete the armor. Unfortunately, there is no legendary nor epic weapons here.
Katagawa Ball is the boss at the end of the Space-Laser Tag story mission. After fighting through Skywell-27, Katagawa Ball must be defeated in order to retrieve the second piece of the Vault Key.
Katagawa Ball has heavy armor and an immense amount of shield (two thirds of its health are made up of shield). To defeat it, use corrosive damage on the armor, then switch to shock damage to deplete its shield. Shooting the plating on the sides of the ball disables the rockets and makes the fight easier. Because Katagawa Ball moves quickly, it is best to keep moving and not let it out of sight.
