Codenames: Undercover is an adult version of the award-winning party game Codenames. The spymaster gives a clue. Can you find the words that match the clue and lead you to victory? Only the spymasters know the identities of their agents. Their team members only see 25 codenames. Each team wants to be the first to make contact with all of its own agents. The spymaster gives clues in the form of single words that relate to several words on the table. If their team guesses an agent from the opposing side, it gives that team an advantage. If they guess the assassin, they lose immediately. Players can also mix the word cards from Codenames and Codenames: Undercover.
