The Black Plague Spreads Friday, September 23rd
Don't miss this week's Zombicide: Black Plague Releases on Friday, September 23rd. You can pick up several new expansions for your game, including Special Guest Artist Boxes with new Survivors from Adrian Smith, Paolo Parente and Jovem Nerd. Of course, with all the new heroes, you’ll need new Zombies! The Deadeye Walkers box has that covered. Other releases include the Black Plague Plastic Token Pack, Black Plague 3D Doors, and the Zombicide Compendium 2!
PS my advice would be to preorder so you get on the queue. unless u r ok just waiting for a while
