Countdown: At long last, an extraterrestrial civilization reached out and made the First Contact. The end of their message showed humankind how to access a mysterious game.

Just yesterday, Ben was a petty criminal getting by on fleecing New York’s one-percenters. Today, he's got a new face, a new name, and a new world to navigate. And Ben’s thinking maybe this time around, he’ll use his skills at disarming and deceiving to help out people other than himself. Maybe.

When the cultivators came to Earth, they destroyed our entire civilization in a matter of hours. Armies fell, cities burned, and that was before the moon turned red and filled our world with monsters. Now, over a decade later, what's left of humanity slaves under the heels of our Qi-infused masters. The luckiest of us might even become one of them, they say—if we serve the Dynasty well enough and harness the power of Qi. But I want none of that. I'm sick of serving, and I want nothing to do with their world. Instead, I want them to pay for what they did to mine.

Matt's just an ordinary guy, but when he's beaten, robbed, and left for dead, bleeding out at the bottom of a gully, it all has to change as he grasps frantically at his only chance for survival, coming as it does in the form of a glowing, dangerously pulsing light. With his reality forever altered, Matt must quickly find a suitable place to deploy the Dungeon Core, fighting his way through the hundreds of people between him and safety, because if he doesn't do it soon, a Core Detonation will solve all of his problems for him....permanently.
