​My blood is poison. My oath is sacred. And my will is ironclad.

Since fleeing my birth pod and finding my legion, I have disappeared from what remains of Silo. I thought my biggest worry was stopping the Myrmidons from creating a circuit of powerful bionics, but I was wrong—so wrong.

The Y-506 virus has made me a lethal weapon to everyone around me, and the blood-thirsty leviathans have become an even deadlier threat to this realm. They're not the simple beasts they used to be. If given the chance, they'll ruin everything my legion and I have fought for.

In this game of hunt or be hunted, none of us are safe.

We train, we fight, and we kill, all beneath the protection of the Outliers. Together with them we will unearth our true strengths and put a stop to the havoc plaguing our world. Jon's life depends on it. So does mine.

We are the Crater Knights, and we're coming.
