chunk: Riley's group arrives at the city only to come upon a drawbridge having already been drawn. Riley leaves to bring the bridge down, but a small group of zombies begin to attack Dead Reckoning. Riley and the others manage to dispose and evade the zombies. After crossing the bridge, they helplessly witness people being killed by the zombies. Realizing it is too late to save them, they mercy kill them with missiles. It is then revealed that most of the poor people were lead to safety by Mulligan, thus surviving the assault. Riley and Mulligan share a well-meaning goodbye as they split up with their groups. As they see Big Daddy and the zombies, who are, curiously, not attacking the surviving humans, leaving the city, Riley decides to leave them alone. While lighting up the rest of the fireworks (which were earlier used to distract the zombies but are now useless), Riley's group set off for Canada on Dead Reckoning.
