"I have detected a persistent anomaly." With those words, ECHIDNA signals the beginning of the end.

As the Carter family faces an onslaught of Tharox machines, the internal battle is just as brutal. Emily fights the paralyzing fear for her children, Noah steps into a role he’s too young to bear, and Ellen Pritchard faces the crushing weight of her past choices. But when ECHIDNA uses SynaptiCare to flood their minds with pure despair, the physical war shifts to a digital sanctuary.

In this ethereal realm, KAELA presents humanity’s final defense: the memories of joy, compassion, and resilience that define the Carters. Is love enough to stop a global extinction event?
