Full Attack

"Captain Ninomiya's Full Attack Hound! Such firepower!"

- Haruka Ayatsuji

Full Attack is the activation of Gunner Triggers through both the Main and the Sub.

Appearance
The appearance of Full Attack depends on the two Gunner Triggers in use. To start it, a Shooter manifests one trion cube in each hand which can later be divided in smaller portions. Gunners summon one firearm the Main and one through the Sub.

Overview
Full Attack could not have existed until the creation of Gunner Triggers and the establishment of the Main/Sub division.

Abilities
By going into Full Attack, the user activates two Gunner Triggers, one through the Main and one through the Sub, attempting to crush the opponent through sheer firepower. Since they will be unable to summon a Shield quickly, this technique is used when one can afford to focus exclusively on attacking. It also has low flexibility, since the user can only use one type of Gunner Trigger. By concentrating on a single target or area, a Shooter or Gunner can wear down and tear through the opponent's defenses, making up for the relatively low power of Gunner Triggers with the number of shots. Unlike Asteroid, Hound and Viper can be used behind cover due to being able to curve, reducing the risks for the Shooter. Experienced combatants can pretend to be preparing to open fire in Full Attack when they are actually ready to switch to Full Guard, so as to lure a hidden enemy into attacking and reveal their position.

The power of Full Attack is dependent on the type of bullet used as well as the Shooter's or Gunner's trion levels. With Viper, Rei Nasu was able to breach the combined Shields of Tatsuya Kuruma and Taichi Betsuyaku. Masataka Ninomiya was able to bombard a moderately large area with his Full Attack Hound, and despite the shots being so scattered they were able to open gaps in Yūma Kuga's Shield.
