They say, "you can never go home again." And, well, if your town is overrun by a necromancer and their zombie horde, they're right. But Anne's not going to just let things stand. She's headed back to clean the place up. That's where you find yourself in the new Zombicide: Black Plague scenario from CMON, available to download now.
From the post:
Ann learned that her childhood village has been devastated by a necromancer: the church’s priest she trusted as a kid. Now, she will hunt him down and take her revenge!
