You and your partner are on a secret mission. However, there are suspicious people in the city where your agents are located. Your goal: contact all 15 agents and successfully avoid a gang of enemy assassins.
You know the agents your partner can safely contact, and your partner knows the agents you can safely contact. By giving a one-word clue that points to multiple words on the board, you will try to find all the agents before your time runs out.
The board game Codenames Duet contains 400 new words, so you don't need any other Codenames game to play. On the other hand, if you own the original board game Codenames or the board game Codenames Pictures, you can combine them to get one large secret agency with a lot of agents in the field to find.
