In the newest edition of Witness, exactly four players join together as members of the secret „Witness Agency“ to fight crime and solve mysteries! In this cooperative campaign game with 8 linked cases, players first read an introductory prologue then are given separate sets of clues to review and memorize.

A case unfolds over four rounds, where a pair of players will be directed to whisper the facts they know to a specific person, in addition to every detail they’ve learned from previous rounds. After keeping everything collected in memory for four rounds, players will be allowed to write down notes for whatever they can recall, before secretly answering three questions about the case. The team’s final score is a total of all the correct answers, up to a maximum of 12.

Witness is filled with both tension and laughter as the Witness Agency’s best agents struggle to keep their facts straight as they chase after the truth.
