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 a standard version and an alternative branded version with a different Sub Weapon and Special Weapon equipped, or will receive one in future DLC.

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.

 Shooter Sub Classes

 Roller Sub Classes

 Charger Sub Classes

 Slosher Sub Classes

 Splatling Sub Classes

=Sub=
 * Burst Bomb - 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 splatter an opponent.

 * Splat Bomb - The Splat Bomb is the standard Sub Weapon. It is a pyramidal container filled with ink that explodes after a short period of time.
 * Splash Wall - The Splash Wall forms a barrier made of falling ink that prevents enemy movement and fire.
 * Sprinkler - 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.
 * Squid Beakon - The Squid Beakon is a device that allows teammates to Super Jump directly to its location.
 * Suction Bomb - The Suction Bomb sticks to walls and other surfaces, exploding shortly after.

=Special=
 * Bomb Rush - The Bomb Rush allows you to throw unlimited Splat Bombs, Burst Bombs, Suction Bombs, or Seekers without consuming ink for a short time.
 * Bubbler - 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.
 * Echolocator - 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.
 * Inkstrike - The Inkstrike can be placed using and causes a large, swirling vortex of ink to appear.

 * Kraken - 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. You cannot have a Splat Roller with the Seeker and Inkstrike, as there is no predefined set for the Splat Roller that includes the Seeker and Inkstrike.

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.
