Zeppelin Attack!: Doomsday Weapons (2014)

"The first expansion for the Zeppelin Attack pulp-themed Zeppelin card game. It adds several new types of cards: atomic attacks and defenses, experimental attacks, science zeppelins, as well as new cards of the existing types from the base game. This expansion adds a lot of variety to the game. Dominate the skies...and your opponents! This is not a stand-alone game, the base game is required to play. "
