Alternative Fire mode

Alternative Fire modes (or alt-fire modes) are unique methods of attack featured on many guns in Borderlands 3. While the manufacturers listed below create weapons with alternative fire modes available (the manufacturers excluded from this list, Jakobs and Tediore have no alt-fire modes on any of their weapons), not all weapons manufactured by them will have alternative modes.

Alternative Fire modes by Manufacturer

By default, a weapon's Alternative Fire mode depends on its manufacturer. All regular weapons of these manufacturers will have a variant of these. The only exception are unique and legendary weapons.

Atlas

Atlas weapons shoot a tracking round. After applying the round to an enemy, all regular shots will target the tracked enemy for a time dependent on the nature of tracking round fired; the general rule is if the tracking round on the weapon is capable of tagging multiple enemies at once, then the tracking duration will be shorter. Tracking rounds automatically replenish their on-weapon stock after a few seconds, with some options needing longer to regenerate.

There are different types of tracking rounds:

• Tracker Dart: A singular dart is shot which can track one enemy.
• Tracker Burst: A small number of darts are shot in a shotgun-like burst. It is possible to track multiple targets if the darts connect with more than one enemy.
• Tracker Puck: A magnetic puck that sticks to the enemy it's shot at. Upon the target's death, it will drop off and has a chance to seek out a new target within a small radius. The puck's tagging effect lasts for eighteen seconds
• Tracker Grenade: A grenade-like charge that is shot in an arc, and will rise up on impact with terrain and explode into hundreds of darts that will track all enemies within the burst radius. The grenade can prematurely explode on directly impacting an enemy. The grenade's tagging effect lasts for twelve seconds.

Dahl

Dahl weapons switch between two different firing modes. This will change the behavior of the gun as well as the sight's zoom.

Of the following, two are available per weapon:

• Semi-Auto: Single shots; usually combined with a stronger zoom
• Burst Fire: A burst of typically around 3-5 bullets
• Full-Auto: Holding down the trigger will fire continuously; usually has the weaker zoom

Maliwan

Maliwan weapons can switch between two different Elemental Damage types.

Torgue

Torgue weapons can switch between their regular explosive projectiles and sticky explosives. Once stuck, these sticky bombs will rapidly explode in sequence of impact when the weapon is reloaded, the mode is switched or the character switches to another weapon. Each successive stuck projectile will do more damage depending on how many rounds detonated before it, for possibly extraordinary amounts of single-target damage.

Vladof

Vladof weapons have various underbarrel attachments that offer a different way of dealing damage. Switching between those is - at least on larger weapons like rifles - represented by rotating the barrel so that the currently active option is on top. If both regular barrel and attachment are minigun barrels they will instead rotate by 90°, activating them both. Vladof underbarrel attachments include:

Pistols:

• Taser: Tasers fire in a slight arc and will continuously deal damage to both enemies directly hit and enemies around the taser itself, which means even missed tasers can still do damage if the user can keep enemies in the taser's vicinity. Uses ammunition from the character's ammo reserve rather than the current magazine, and regenerates itself after a few seconds.
• Zip Rockets: This attachment fires tiny rockets in a straight line. It has its own magazine which will regenerate after a short time.
• Second Barrel: A secondary barrel below the regular one. The barrels rotate after every shot, increasing the fire rate of the weapon. This attachment is automatic and can't be toggled.

Assault Rifles:

• Grenade Launcher: Does not draw from the current magazine and has a varying maximum of grenades that can be launched at one time. Regenerates one grenade at a time.

Assault Rifles/Sniper Rifles:

• Bipod: Switching modes deploys a bipod that drastically improves Handling and Accuracy, but reduces movement and aim speed.
• Shotgun: Possesses variable projectile counts and pellet damage statistics, and like the grenade launcher attachment, the weapon regenerates one shotgun round at a time separate from the main magazine but will draw each round from the user's current ammo reserves. Each shot of the shotgun will take one bullet.

Sniper Rifles:

• Rockets: Similar to the Assault Rifle's Grenade Launcher, this attachment grants additional explosive projectiles. The amount of Rockets can vary.

Heavy Weapons:

• Micro-Rockets: This alters the method of projectile delivery, rather than being an alternate weapon attached and draws from the current magazine of the weapon. Fires a swarm of smaller missiles to bombard an area instead of a single large rocket.
• Big-Boy Rocket: The damage dealt by this single rocket is at least double, and sometimes triple that of the normal rocket fired. Regenerates its round relatively slowly, but does draw from reserve ammo pool and not the current magazine.
• Mortar: Designed to assault enemies behind cover. Regenerates its round relatively slowly, but does draw from reserve ammo pool and not the current magazine.

Notes

• Unique and legendary weapons can differ from their manufacturer's regular Alternative Fire Mode in various ways. Examples include:
  • The Vortex Grenade utilized by Ruby's Wrath is a variant of the Atlas Tracker Grenade. It is fired at a noticeably higher velocity and will bounce forward instead of stopping on the first impact with terrain. When it explodes, however, it creates an effect identical to a singularity grenade in addition to tracking all enemies in range. The grenade's tagging effect lasts for eight seconds.
  • Malak's Bane and ASMD switch between different projectiles.
  • Cloud Kill and Krakatoa do not have the ability to switch modes at all.
  • The Hornet has fixed burst fire and only toggles zoom magnification on mode switch.
  • Brashi's Dedication switches between shock and corrosive damage like a Maliwan, despite being manufactured by Dahl.
• Switching Fire Modes takes a little bit of time. Mode Switch Speed is affected by the same modifier as Weapon Switch Speed.
