The Eaten By Zombies: Weapons of Mass Destruction mini-expansion consists of 5 sets of swag cards which were unlocked during the Kickstarter funding of Eaten By Zombies!: In Cahoots. These swag cards all help killing zombies, which is a change in the dynamic of the Eaten By Zombies!: In Cahoots which mainly consisted of swag to flee from zombies. These new cards may prove to make the difference when trying to survive from the zombie hordes and win the game.

The cards are:
- Pineapple
- Double Barrel Boomstick
- Flame Thrower
- Six Shooters
- Molotov Cocktail
