The zombie plague was created by the Necromancers in order to forward their nefarious agenda. Each of these evil sorcerers has their own goals in mind, and each has their own specializations. One thing unites them: the desire to eradicate the living and control the dead. For this, they create hulking abominations, nearly-perfect killing machines that are almost impossible to destroy. The Green Horde: Special Guest Box -Adrian Smith allows players to expand their games of Black Plague with a new Necromancer as well as two new monstrous abominations. They can be used to replace the regular Necromancer and Abominations to add an extra degree of difficulty for the Survivors. This is an expansion. The Zombicide: Black Plague or Green Horde core game is required to play.
