The Twin Grakatas are the akimbo secondary version of the primary Grakata assault rifle. They have the ability to fire two bullets at once due to their 2 base multishot, being the second non-shotgun weapon to possess a multishot stat greater than 1 after the Akjagara. They also consume two ammo per shot, depleting their high ammo pool alarmingly quickly.
The Twin Grakatas fire two bullets per shot. This means that the actual fire rate is double that of the listed fire rate.
The listed damage for the Twin Grakatas is split between the two bullets per shot, meaning the damage per bullet is half the listed amount.
The total credit cost of crafting the Twin Grakatas, including the blueprint and the building costs of its two constituent Grakatas, is 195,000 195,000.
Compared to the Grakata, each individual bullet will deal 4 impact, 3.35 puncture, and 2.65 slash, which is less damage per bullet than the Grakata, but fires two of these at once, resulting in far more DPS. The weapon also has the advantage of a much more efficient physical damage mod as well as Lethal Torrent, causing the Twin Grakatas to deal more damage in the end as well as more DPS.
The Twin Grakatas appear to have been inspired by a popular fan-made comic by Datareaper (who was the designer of the Kronen) involving a GrineerLancer named Clem, who idolizes the Tenno and is seen wielding two Grakatas as his signature weapon.
The Twin Grakatas are the first weapons to occupy a different weapon slot to their default counterpart - while the single Grakata is a primary weapon, the Twin Grakatas are considered secondary weapons, and thus use pistol mods instead of rifle mods.
Due to this point as well as the weapon's stats, it also possess the highest possible ammo reserve -2,280- of all equippable weapons (barring Archwing weapons, which have an infinite reserve).
Along with the Spira, The Twin Grakatas are one of the few secondary weapons that can achieve orange critical hits, using a combination of Primed Pistol Gambit, Creeping Bullseye, and Hydraulic Crosshairs after the player manages to hit an enemy's head. This will increase the critical chance to 117%, enough for every shot to crit and cause about 17% of the shots to become orange criticals.
