Similar to expansions such as Washington Z.C. from Zombicide: 2nd Edition, and Gears & Guns from Zombicide: Undead or Alive, Eternal Empire is a campaign expansion. It consists of 10 Quests that form a single ongoing story that the Survivors go through, accumulating experience, skills, and equipment as they go. Their actions and choices on each Quest may have either positive outcomes or dire ramifications down the line. Youll even be able to carry over equipment from previous Quests!
