Voss knows who Jack really is. He doesn't want Jack to fix things – he wants Jack to optimize the weapon生产线. "You built the locks, Mr. Mercer," Voss says, holding a photo of Jack's estranged daughter. "Now you'll teach us how to pick them. Or she visits the Silo next."
Jack doesn't fight the warden. He fights the room . He lures Voss and his elite guard squad into the main generator hall. Using his knowledge of the building's resonant frequency, he drops a series of hammer strikes on a support beam – wham, wham, WHAM – causing a cascading structural failure. The floor collapses beneath the guards. The AI hub crashes. The main blast doors, designed by Jack, cycle into a permanent lockdown with Voss inside the empty cell block .
"I didn't destroy it. I just restored the factory settings."
He came to serve time. He left to serve justice.
