The Broodmother is a giant spider that spawns numerous Araneos. For Gamma, 10-15 high-level Megatheriums (20k HP, 500% Melee) and a Yutyrannus are sufficient. For Beta and Alpha, aim for 18-19 Megatheriums with 30k+ HP and 800%+ Melee, along with a Yutyrannus and 1-2 Daeodons for healing. Equip your survivor with a good Shotgun or Assault Rifle and plenty of ammo. Focus fire on the boss, letting the Megatheriums handle the adds.
