Everybody knows that you should keep your distance from zombies. Those teeth and claws are the most dangerous part. Best to pick them off from afar with crossbow bolts. Hey… is that a zombie with their own crossbow? Better duck!
The Crossfire Pack for Zombicide: White Death brings bolts aplenty for both the players and the zombies. It includes Crossbow Guards, ready to take out zombies from afar. However, there’s also Deadbolt Zombies, who can still just barely use their own crossbows to deal out wounds from afar. Turn-about is fair play, as they say.
