Social Deduction Chaos in the Good Cop Bad Cop Zombies Expansion

About Good Cop Bad Cop: Zombies, from BoardGameGeek:

The Zombies expansion to Good Cop Bad Cop removes player elimination and adds an immediate and growing threat from a third team, the Zombie team. When a non-Leader would previously be eliminated, they instead join the Zombie team. They win if they can Bite a wounded Agent or Kingpin. The Honest and Crooked teams still have the same winning condition of eliminating the opposing leader, but they will have to do so while holding back the zombie horde. The new equipment to this expansion, like Chainsaw, Shotgun, and Machete, are the most deadly we've ever added. Use it carefully or you might end up creating more zombies! -description from publisher
