In Borderlands 4, players can discover more than 8 Legendary Heavy Weapon Ordnance, each providing a distinct gameplay experience that can significantly impact build effectiveness. Those focusing on Heavy Weapons and Ordnance need to determine which weapons are best suited for their playstyle, particularly when certain builds enhance Ordnance damage and ammunition capacity. Below, we delve into the specifics of each Legendary Heavy Weapon Ordnance in Borderlands 4, their boss and mob effectiveness, and the means to acquire them.

Sidewinder

How to Acquire the Sidewinder Heavy Weapon in Borderlands 4

• Obtained from: Gilded Glory Pack DLC. Available as a random loot drop in the world or from Golden Chests.
• Weapon type: Sidewinder

The Sidewinder is a capable Rocket Launcher that releases two rockets simultaneously. The initial projectile targets a point, and upon detonation, a second rocket launches, homing in on another target. While it has decent performance, its restrictive access–being tied to a Pre-Order bonus and DLC–and lack of farming options make it less appealing for some players.

Sprezzatura

How to Acquire the Sprezzatura Heavy Weapon in Borderlands 4

• Obtained from: Random loot drops in the world or found in Golden Chests.
• Weapon type: Gungnir

Sprezzatura takes inspiration from Norse mythology, offering effects akin to Odin’s spear, Gungnir, which always finds its mark. When fired, the rocket ascends before seeking its target and exploding on impact. Though marketed as a homing missile, its functionality can be inconsistent, requiring a specific distance for effective lock-on. With only two shots, it’s not ideal for crowd control but can be effective against bosses at a distance.

Ravenfire

How to Acquire the Ravenfire Heavy Weapon in Borderlands 4

Ravenfire features a unique firing arc typical of Torgue weapons; upon impact, it disperses into several smaller cluster explosions. While it may be useful for taking down dense groups of enemies, stronger Heavy Weapon options and better grenade alternatives exist for crowd control, leaving Ravenfire feeling somewhat underwhelming.

Inkling

How to Acquire the Inkling Heavy Weapon in Borderlands 4

• Obtained from: The Divisioner, «The Wireworks» Order Bunker, The Low Leys, Terminus Range.
• Weapon type: Inkling, with bouncing projectiles creating an Elemental Splat effect.

Inkling is one of the limited Legendary Gatling Guns available, and it performs admirably. Its projectiles have a slow firing rate but deal splash damage, affecting the target and the surrounding area with the associated elemental effect. For instance, a Radiation variant would leave a poisonous area, rewarding players who specialize in Ordnance and Elemental damage through sustained fire.

Gamma Void

How to Acquire the Gamma Void Heavy Weapon in Borderlands 4

• Obtained from: Moon-Maddened Callis, Elpis Orbital Shatterfield, Fallen Crown, Carcadia Burn–available post Main Mission: Another Day, Another Universe.
• Effect: Creates a Singularity for 10 seconds, causing enemies within it to suffer +40% additional Radiation Damage over time.

The Gamma Void acts like a miniature black hole, drawing in enemies while inflicting Radiation Damage. This weapon’s effectiveness is enhanced for players who focus on Radiation Damage and Ordnance abilities, as it continuously harms enemies within the Singularity’s area. However, its long cooldown and single ammo charge can limit usage compared to other options.

Disc Jockey

How to Acquire the Disc Jockey Heavy Weapon in Borderlands 4

• Obtained from: Sidney Pointylegs, «The Prospects» Ripper Drill Site, Hungering Plain, the Fadefields.
• Effect: Energy disc projectiles bounce up to 5 times, gaining +20% Damage with each bounce.

Disc Jockey is highly beneficial for players with Ordnance-focused builds, as each Energy Disc bounces multiple times while increasing damage with each impact. This can lead to devastating efficiency, especially in boss encounters where the bouncing discs can continuously strike targets.

Streamer

How to Acquire the Streamer Heavy Weapon in Borderlands 4

• Obtained from: The Oppressor, The Killing Floors, Dissected Plateau, the Fadefields–available post Main Mission: A Lot to Process.
• Effect: Fires stationary projectiles that emit a damaging beam.

The Streamer launches projectiles that remain in place and unleash a continuous beam that damages enemies. When utilized with specific skill tree investments that allow for infinite ammo, players can effectively cover an area with damaging beam fire, making it particularly effective against stationary or large targets.

Bottled Lightning

How to Acquire the Bottled Lightning Heavy Weapon in Borderlands 4

Bottled Lightning sends out a slow-moving orb that shocks and electrifies enemies in its path. While the shock radius is limited, it can still inflict significant damage. Upon contact, it detonates, making it effective for crowd control. Players benefitting from specific ammo recharge skills can also find great utility in this weapon for sustained use.

Atling Gun

How to Acquire the Atling Gun Heavy Weapon in Borderlands 4

• Obtained from: Callous Harbinger of Annihilating Death, «Craven’s Nook» Order Bunker, Heart of the Mountain, Terminus Range.
• Weapon type: Whistler

The Atling Gun stands out for its increased fire rate the longer the trigger is held down. It can eliminate enemies rapidly, especially when integrated into a build that recycles ammo. Its rapid-fire capabilities and the potential for elemental damage make it a formidable option for both mobs and bosses.
