Corporal Brennan Boss Loot & Location in Borderlands 4

by

Corporal Brennan is a boss enemy in the first story pack for Borderlands 4, called ‘Mad Ellie and the Vault of the Damned’. This guide will tell you where to find him and what valuable Legendary items he might drop when defeated.

This guide will tell you exactly where to find and defeat Corporal Brennan in the Crooked Teeth area. We’ll also explain how to use his special Legendary weapons – the Laser-Cutter and Bismuth-Tipped Dagger – to help you take down enemies effectively.

Corporal Brennan Location & How to Beat in Borderlands 4

  • Corporal Brennan can be found in Crooked Teeth at the Trans-Lunar Intactment, which is just north of the Ellie’s Garage Fast Travel Station.
  • Alternatively, you can head into the Speakeasy and take the south portal, which will teleport you directly before the boss room!
  • Corporal Brennan is a mech whose first health bar is Shield (blue), so use Shock and Radiation.
  • For the second health bar, you’re dealing with Armor (yellow), so use Corrosive or Cryo to make short work of his non-threatening attacks.

Corporal Brennan Loot Drops in Borderlands 4

Legendary Item Type Special Effect
Laser Cutter Legendary Vladof Assault Rifle Bone Saw (Fires laser beams)
Bismuth-Tipped Dagger Legendary Grenade Ordnance Bismuth – Attaches on Hit. Enemies take 15% more elemental damage for each attached Dagger.

This downloadable content features several nods to the game Dead Space, and the Laser Cutter is a particularly clear example. Its description jokingly calls it “Isaac’s bestie,” referencing the Plasma Cutter weapon used by Dead Space‘s main character, Isaac Clarke. This makes the Laser Cutter a great choice for fans who appreciate the tribute.

The Bismuth-Tipped Dagger is also a strong choice. Its ability to deal 15% extra elemental damage per dagger stuck in an enemy could lead to some very powerful combinations. We suggest keeping an eye out for both of these items.
