GSO Gigaton Cannon

Trivia

 * Due to the shells being affected by gravity, the Megaton Cannon, the Gigaton Cannon, and the Three-Pound Cannon are capable of adjusting their projectile arc when attacking an enemy at longer ranges by increasing their firing angle. This makes them effective mortar substitutes.
 * The Chinese translation simply refers to it as "京級巨炮", which is nothing more than an inaccurate, pronunciation-based translation. A more literal translation would be "十亿吨重炮", as Giga is the equivalent of 1 Billion.
 * Like certain turret guns, the Gigaton Cannon's sprite only takes up 16 cells technically, with the rest of it reserved for the cannon's rotation.
 * The prefab name implies that the Gigaton is a variant of the Megaton.
