Which two weapon classes did Splatoon 2 add to the series?

Splatoon 2 added the Dualie and Brella weapon classes to the series.

Dualies are paired pistols wielded one in each hand. Their defining ability is the dodge roll: while firing, the player can roll in a chosen direction and briefly gain a more aggressive firing stance. This gave Splatoon 2 a mobile, close-range option unlike the single-gun Shooters in the original game.

Brellas resemble umbrellas or parasols. Their canopies can open to block incoming attacks, creating a defensive weapon class that also supports unusual tactics such as launching or separating the canopy. Different Brella models emphasize different combinations of shielding, range, and firepower.

The original Splatoon launched with classes including Shooters, Chargers, Rollers, Splatlings, Inkbrushes, Blasters, and Sloshers. Splatoon 2 expanded that foundation with Dualies and Brellas; Splatoon 3 later added Stringers and Splatana. Blasters and Rollers are therefore tempting but incorrect choices: both were already present in the first game.
