This is an expansion for Codenames and/or Codenames Duet. You will need the base game to play.

What happens after a mad scientist rides a sandworm into an asteroid belt? Explore the universe of possible outcomes in the Codenames Sci-Fi pack!

Codenames: Sci-Fi Expansion Pack features a themed set of 50 words, carefully chosen to spice up your game of Codenames or Codenames: Duet. Simply mix the new cards into the basic set of words, randomly or in whatever ratio you like, or even play two full games using only the 25 cards in this pack.

Aside from new words, the pack also includes 3 new agent tiles (2 for Codenames and 1 for Duet), and 4 sci-fi-themed pictures for Codenames: Pictures to customize your games even more.
