This trophy can be tough, unless you have the right teammates. You'll want to have someone on your team max out the Hand Boosters, so you can reload faster. Use the strategy from  Survived Nightfall, and have everyone shoot at his face in between his attacks to get him down quickly. When he goes down, have everyone shoot the orange sack on his side, as it will take off a large amount of his health when it explodes. During Half-Time, kill all of the aliens as fast as possible.

If some people have Hypno Knives, along with the "Hypno a Rhino" upgrade, they can turn the Rhinos instantly, making this go much faster. When the Breeder comes back, use the same strategy, and keep your eyes out for the flowers that will regenerate his health. If you see one, destroy it immediately. Just keep shooting at his face, at all times. With the firepower of everyone on your team, you will be able to take him down very quickly. The Venom-X also does a good amount of damage to him if you have the ammo for it. Use all of these tips to take him down in five minutes and you'll earn the trophy.
