When activated, the Killer Wail projects a series of concentric circles in its intended path for a moment before firing massive sound waves in the user's Ink color shortly after. They splat any enemies they touch, ignoring buildings or other obstacles. While the Killer Wail does not spread any Ink of its own unless an opponent is splatted, it is useful for gaining or keeping control of the stage.
|“||Killer Wail is an extremely powerful special, ideal for splatting opponents caught within its lethal sonic cone. When activated, you’re prompted to aim the device, which appears like a large megaphone. In addition to rotating the device, you can also tilt it, aiming it up or down. Once set, shoot the Killer Wail to send a sonic blast through the stage. This wave travels through the entire stage, passing through walls and other objects. Given the special’s linear attack, aim it down narrow corridors or high-traffic chokepoints. While the Killer Wail doesn’t spread ink, any opponents unlucky enough to be caught within its blast will explode, spreading your team’s ink over a small area.||”|
