Trophy description - Kill the Breeder in less than 5 minutes in Nightfall in Regular or Hardcore difficulty. .

Trophy - Bronze

It is unlikely, but not impossible, that you kill the Breeder within five minutes in your first attempt.

The counter begins as soon as the Breeders health appears on screen.

you need to go full berserk on the Breeder and rain hell on him. The trick is 80% focus on the Breeder, 20% on everything else. Instrumental to this goal are the highly or fully upgraded portable manned turrets, the Venom-X and good LMGs or ARs. All team members must focus on the Breeder, while being mindful of the enemies, the red mist, the Rhino and, for non-Medics, the Scorpions acid spit. Also proximity without vulnerability is key. Be mindful of his tactics and always keep a lookout for the flowers that sprout on the three corners as they will delay his demise, and cost you precious time. Make sure you keep each other steadily supplied and adequately shielded. In focusing on the Breeders health one is bound to lose track of their own.

To be sure, the guide authors team achieved this objective without reliance on portable turrets. So a turret might not be absolutely necessary, however it can really incrementally increase the odds.
