The .52 Gal is in a set with the Splash Wall and Killer Wail. Each shot consumes 1.2% of the ink tank capacity, which allows 83 shots to be fired, so it packs a serious punch. Since it has a low rate of fire, careful aiming is required in order to hit opponents.
"A high-powered weapon that pumps out a lot of ink with each shot. Doesn't take many shots to splat an opponent, which is a good thing given its rather slow rate of fire."
The .52 Gal returns in Splatoon 2, with an identical appearance but slightly changed performance. It comes with the S2 Weapon Sub Point Sensor and S2 Weapon Special Baller. Each shot consumes 1.3% of the ink tank capacity, allowing for 76 shots to be fired per tank.
