Raising a Queen at the End of the World - Episode 30

You're sparring with ten zombies on the sixth floor while Ivy, who plans to protect her dad, prepares to kill evolved shamblers to harvest cores. She doubts training alone can change shambler biology but hopes cores will help. Mid-spar you feel a tug: a puppet spots a huge mutated zombie dog in the base. The six-foot, muscular beast kills a low-level puppet instantly. You send Titan; it overwhelms the dog with its hammers, crushes the dog's front paws and finishes it with a fatal stab. The episode ends with the base exposed to stronger evolved threats.
