What to know

  • Booming Transmitter is a legendary grenade ordinance manufactured by Ripper in Borderlands 4.
  • It is typically obtained as a pre-order bonus via the Gilded Glory Pack.
  • Upon explosion, it releases projectiles from nowhere that track and hit enemies.
  • The grenade features increased explosive damage and special effects enhancing damage against elite enemies.

Booming Transmitter is one of the more unusual Ordnance items in Borderlands 4. Instead of traditional firepower, it gives you a deployable drone that supports briefly in combat. Because it’s tied to pre-order bonuses, though, there are limits to how and when you can use it.

What the Booming Transmitter does

When thrown, the Booming Transmitter creates a stationary drone that stays active for a short duration. The drone’s lifespan is only a few seconds, but within that time it can add an extra layer of utility or distraction in fights. This makes it situational but potentially useful for controlling enemies or buying time during harder encounters.

How to get the Booming Transmitter

Booming Transmitter is not part of the regular loot pool. Instead, it was included as a pre-order bonus with certain editions of Borderlands 4. That means:

  • If you pre-ordered the game, and have the Gilded Glory pack, it should already be in your inventory.
  • If you didn’t, the item won’t drop naturally during play.
  • The grenade spawns at level 30.
  • Some players without the right edition can see the item but cannot equip it.

As of now, there is no confirmed farming location, boss, or chest that drops it.

Booming Transmitter effects and stats

The Booming Transmitter offers:

  • Explosive grenade damage increased by around 21%.
  • Additional 10% damage dealt specifically to "bad butt" enemies, or tougher ranked foes.
  • The unique effect where after the explosion, numerous projectiles suddenly fire, striking enemies from what appears to be thin air.
  • Manufacturing by Ripper lends specialized grenade traits such as teleportation of the grenade trajectory toward target locations, similar to a guided longbow.

This combination results in a grenade that delivers strong burst damage plus follow-up target hits, enhancing both area and single-target effectiveness.

Gameplay tips for Booming Transmitter

To maximize this grenade’s potential, use these approaches:

  • Throw the grenade where enemies cluster to benefit from the explosion and the additional projectile barrage.
  • Combine with grenade-boosting gear or skills that increase explosive damage to amplify output.
  • It’s especially handy against boss enemies due to the boosted damage on elite foes and the sustained projectile hits after detonation.
  • Experiment with character builds that synergize projectile or grenade damage bonuses for best results.

The Booming Transmitter offers a visually striking and tactically smart grenade option in Borderlands 4. It’s a rare collectible tied to early game bonus content and offers a mix of explosive force and rapid follow-up assault, rewarding strategic throws and build synergies. For players aiming to diversify grenade playstyles, it’s a worthy choice to seek out and master.
