The Breeder is a large, spider-like creature that is armed with large claws. In the trailer, the Breeder is seen stabbing a person in the chest with sharp claws. It has two basic attack of shooting and spawning eggs that contain the Cryptids. When facing a Breeder, it is best to shoot at its head to damage it. The Breeder has a health bar that is located at the left corner of the screen.
The Breeder has a powerful melee attack that nearly downs any player. It cannot use this attack while using another. It also has a machine gun attack. When using this, two guns that does massive amounts of damage and have an extremely high rate of fire will spring out and fire at the players. They can only target one player at a time and will retract if there are no available targets. It is also capable of launching large clusters of gas. This gas does more damage than that of a Scorpion and lasts far longer. The medic upgrade for gas immunity does not protect against this. It also can fire off eggs in groups of three. These eggs will grow larger until they hatch into Hunters, however, they are very vulnerable whilst growing. Trophy Systems do not block any attacks. In the final encounter with the Breeder, at the end of Nightfall, two Cryptid spires stand at either side of the Breeder. These can spawn Hives with sort of neural enhancer that connects with the Breeder, and whilst connecting, the Breeder generates a sphererical shield that prevents the Breeder from taking any additional damage from players. This shield can be easily disabled by destroying the neural hives, however, and the Breeder will fall to the ground, out of breath. Whilst down, the player(s) can go right up to the creature and do as much damage as they desire without being hit by the Breeder. However, after a short while, the creature will regain strength and continue to fight the player(s). When the Breeder dies, it screeches into the air as a sign of defeat and, much like a spider, will fall to the ground and will twitch a bit until it dies.
