Weapon

"As an Inkling, you can use weapons and ink your turf. Be sure to experiment with different weapon sets!"

- Splatoon official site

Weapons are tools used in Splatoon to spread ink and splatter enemy Inklings. They can be purchased from Ammo Knights with Cash earned from online multiplayer matches. Weapons are always in a predefined set of a Main Weapon, a Sub Weapon, and a Special Weapon. Sub Weapons, or secondary weapons, consume considerably more ink than Main Weapons and usually serve specialized purposes limited to specific combat situations. Special Weapons are powerful weapons that can only be used after filling up the Special Gauge by covering enough ground with ink.

=Main= All weapons have two versions: the original, and an alternate with a different Sub and Special Weapon setup and a slightly different appearance. With the addition of Sheldon's Picks, some weapons gained a third version with yet another set of Sub and Special Weapons.



Classes
Sub Classes are a way to distinguish different weapons of one weapon type. For example the Aerospray RG and the Dual Squelcher are both considered Shooter weapons but differ in many ways. A more explicit example would be the Splat Roller compared to the Inkbrush. Those are both considered Rollers, although the Inkbrush is far from being a Roller. These Sub Classes are not officially recognized in-game, but since they have noticeably different playstyles, they are worth unofficially recognizing. Thus, this section shows all types of Sub Classes existing in the game so far.

 Splatling Sub Classes

=Sub=
 *  - The Burst Bomb is a water balloon-esque bomb that explodes on impact. Because it contains less ink than a Splat Bomb, multiple can be thrown quickly and two must be used in order to splat an opponent.
 *  - The Disruptor slows enemies down and lowers their abilities.
 *  - The Ink Mine can be hidden in ink, and will explode after a short amount of time or when an enemy touches it.
 *  - The Point Sensor reveals the locations of enemies and marks them for all teammates to see for easy tracking.
 *  - The Seeker is a mechanical device that follows enemies and leaves a trail of ink behind. Upon reaching its target or after a certain amount of time, it explodes into a large burst of ink.
 *  - The Splash Wall forms a barrier made of falling ink that prevents enemy movement and fire.
 *  - The Splat Bomb is the standard Sub Weapon. It is a pyramidal container filled with ink that explodes after a short period of time.
 *  - The Sprinkler can be thrown onto a variety of surfaces and sprays out spurts of ink in a circular motion for a short amount of time.
 *  - The Squid Beakon is a device that allows teammates to Super Jump directly to its location.
 *  - The Suction Bomb sticks to walls and other surfaces, exploding shortly after.

=Special=
 *  - The Bomb Rush allows the player to use their Sub Weapon with no Ink restriction for a short time.
 *  - The Bubbler is a spherical force field that rebounds enemy attacks and can be spread to teammates. It is available for a short amount of time.
 *  - The Echolocator reveals the locations of all enemies for teammates to see on the field and on the map. It is available normally for twelve seconds.
 *  - The Inkstrike can be placed using and causes a large, swirling vortex of ink to appear.
 *  - The Inkzooka shoots tall, narrow twisters of ink in rapid succession, allowing for quick placement of linear paths and splatting of enemies.
 *  - The Killer Wail blasts a large sound wave in a certain direction that obliterates all enemies in its path and travels through walls.
 *  - The Kraken allows Inklings to temporarily transform into large, invincible, kraken-like creatures with enhanced mobility and power.

List of Weapon Sets
In Splatoon, each weapon comes as a predefined set. For example, the standard Splat Roller comes with the Suction Bomb and the Killer Wail as its sub and special weapons, respectively. It is impossible to have a Splat Roller with Seekers and the Inkstrike, as there is no predefined set for the Splat Roller that includes them.

However, there are alternates of every set. An example of this is the Krak-On Splat Roller, which uses the Squid Beakon and Kraken rather than the Suction Bomb and Killer Wail that the classic Splat Roller sports.

Trivia

 * There are a total of 82 main weapons, 10 sub weapons and 7 special weapons as of Version 2.7.0.
 * To purchase every weapon set, a total of is needed.
