The Dubstep Gun, is a very unique and powerful weapon. It will fire long-range pulses of energy to the beat of an electronic song, the song being determined by the Costume selected for the gun. It has no ammo reserve, instead relying on a charge percentage that regenerates over time. It also needs to charge up briefly before it can be fired.
Each costume for the Dubstep Gun changes the song played in addition to the weapon's model. Unlike other weapons, the change is more than aesthetic, as the rhythm and beat of the song determines the rate of fire and intensity of the shots.
The default costume is white and plays the dubstep track A Bass Renaissance by composer Josh Powell, which is a Dubstep remix of the 1999 track "A New Renaissance" by composer Dave Hewson.
The "Industrial" costume is dark grey and the track is a heavier remix of A Bass Renaissance by Malcolm Kirby Jr.
The "Popstar" costume plays the electro track Vindicate by Datsik and Excision, which is also played on 97.6 K12 FM.
The "Da Wub" costume from the mission Hello Teacup plays Duel by Bare Noize.
The Dubstep Gun seems to be based on the video Dubstep Guns 1 by Corridor Digital Collab.
The Dubstep Gun causes nearby vehicles to fire their Hydraulics. Although Hydraulics are normally unavailable in Saints Row IV, jumping into car immediately after using the Dubstep Gun allows full control of Hydraulics for a short period of time. After a few seconds, the Hydraulics are not be able to be used, but the wheels remain in the last position they were in.
After shooting a car with the Dubstep Gun, camera control is unavailable, as if Hydraulics were enabled, and can not be restored after Hydraulics become unavailable, unless the Hydraulics are manually disabled before they become non-functional.
