The Breaker 12G is a very powerful shotgun that fits into the primary slot, tied with the Mosconi 12G and Joceline O/U 12G in terms of damage, but soars above them with its significantly larger magazine capacity and mod pool size. The Breaker is blessed with a rapid and interruptible reload, allowing the user to retaliate faster when surprised. It also has the largest pellet spread among the three, making it deadlier up close.
Other than that, it features much lower Stability than its competition, and the smallest ammo reserve. It is slower to fire than either the Mosconi and Joceline, giving it a lower DPS overall. To complicate things a bit more is its average Concealment, which is the lowest among the three, making it much less suitable as a compact high-damage dealer.
Take advantage of the Breaker's damage and spread. Unleashing it on enemies up close can be significantly more effective than trying to snipe them down from range.
Close By Aced can be a very effective complement for the Breaker as it allows the player to pump off hipfired shots on the move faster than usual and deal more damage with the target(s) inside the shotgun's effective range.
Shotgun CQB can further speed up the Breaker's already quick reloads.
One or two Ammo bags can help greatly when the player has to hunker down and defend an objective.
Carry a high-accuracy secondary to deal with Snipers and preferrably a high-damage/fast-striking melee weapon to handle other enemy units when in a pinch.
Attaching a gadget that provides a laser sight can be a viable substitute for iron-sights.
Stealth/Dodge players may want to consider attaching the Shh! silencer instead of The Silent Killer Suppressor as Shh! does not block the default "ironsights" of the Breaker.
*The LED Combo is based on the Leapers, Inc. UTG LED Weapon light and Laser. **Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.
The Apex shotgun was a gift from Mike the mechanic to Rust. The axe on the forend of the weapon was installed because Rust would frequently run out of ammunition and resort to using the shotgun as a melee weapon.
It is actually usable in such manner during gameplay though, since the Breaker 12G's Weapon Butt animation involves the player character clubbing/shoving enemies with what seems to be the shotgun's forend. It does not confer a melee damage boost when equipped, however.
The Breaker 12G was based on the 12-gauge version of the Winchester Model 1887, with the default stockless appearance being based on the Mare's Leg variant. Adding the Long Stock restores it to the proper length.
The Breaker's unique flip-cock reload is a reference to Terminator 2: Judgment Day, in which the titular character also performed the stunt while firing the shotgun and driving a motorcycle at the same time. This is lampshaded by Almir Listo in the character spotlight for the Breaker's companion heister Rust.
The Breaker 12G does not have an enlarged lever loop and cutaway trigger guard like in the film however, which would realistically cause the lever to twist and crush against the user's fingers under the weight of the shotgun when the flip is attempted and can lead to severe injuries. Noteworthy, the film had to have a separate, lightened prop version with a widened lever loop for the scenes where it was flip-cocked; Arnold Schwarzenegger, the actor who played the Terminator in the aforementioned film, almost broke 3 of his fingers when he attempted the stunt with the unmodified version.
Reloading the Breaker 12G shows the player character jamming an inordinately large amount of 7 shells in its default 5-shell magazine tube. While it is possible to load an excess of two shells into the shotgun, one of them will have to be chambered while the other loaded into the weapon's carrier.
It also does not gain or lose extra ammo per magazine when fitted with the Long Barrel or Short Barrel, despite the visually altered tube length.
The Breaker 12G is allegedly an heirloom passed down to Rust from his family.
