Inkzooka

The Inkzooka is a special weapon in Splatoon.

Splatoon
When the Inkzooka is fully charged (Or acquired from a canned special in Octo Valley or the Battle Dojo), the player can shoot out large lines of ink pillars for roughly a six-second time period.

The Inkzooka has the second-longest range of any weapon in the game, only bested by the weapons. The E-liters fire up to seven lines of distance in the Shooting Range when fully charged, while the Inkzooka reaches only about six and a half.

Use

 * The Inkzooka is well-suited for taking out camping enemies, especially ones using chargers who often stay out of range of most weapons.
 * The projectile of the Inkzooka is the tip of the tornado. Therefore, if the tornado top hits an overhead obstruction, the whole pillar stops. A way to counter this is to aim downwards, thus decreasing the weapon's arc and avoiding overhead obstructions.
 * An easy way to avoid an Inkzooka is to simply stay out of the user's line of sight. While they can still use their sub weapon, using it wastes some of the Inkzooka's duration for shooting.
 * Without abilities, six shots can be fired from an Inkzooka. If an enemy activates it, listen for how many times they fire; if it reaches six, the coast is likely clear after that.
 * After getting splatted by an Inkzooka user, take note of their main and sub abilities. Two subs will increase the shot total to seven, while one main and two subs will increase it to eight.

Quotes
"This shoulder-fired bazooka-like weapon fires swirling tornados of ink, instantly splatting opponents and leaving behind a narrow ink trail. This is by no means a precision weapon, but while active, you can fire the Inkzooka continuously for approximately six seconds, sending multiple twisters of ink across the stage. But be careful where you fire the Inkzooka. The recoil of each shot nudges you backward. If you're standing near a ledge, this recoil may knock you off the side of the stage. You could also get pushed backward into enemy ink, so make sure the area around your feet is thoroughly coated in your team's ink. The Inkzooka is also difficult to fire when aiming down over a ledge. For best results, activate Inkzooka when you're on the same level as your opponent or just below them."

 * Though the Inkzooka does not return in Splatoon 2, a drawing of one appears on a Sunken Scroll explaining the absence of special weapons. Its role is indirectly replaced by the, in that they both shoot out large explosive ink projectiles.
