Players try to collect secret documents and store them in their safe for points, but assassin, special agent and mole cards make the process tough. Each turn, all players select one card from their hand and reveal them simultaneously, trying to outguess their opponents.
From my 1997 notes:
Card game with nearly 100 cards in full colour. Players simultaneously play cards from their hand and their interaction when revealed provides the 'meat' of the game. Anyway, who could resist a game where, if you don't shout "BOOOM" when you play the Assassin card, you are penalised 50 points!
