Alien on Board

Log entry 87c. from 03/18/2085: After a successful mission on the Janus ring of Saturn, we have initiated the return flight to Earth. Suddenly the alarm system of our board computer switches on: WARNING ... XF33! Alien on board! We quickly meet on the main deck, the entire crew has appeared. Everyone seems normal. And yet the measuring devices report "strange biomass activities"! So - One of us has to be the alien! Who can it be? And how are we supposed to expose it? With specific questions we will try to identify the intruder, otherwise this could be the la...

Aim of the game... ...is to unmask the alien or to mislead the crew members by answering, listening and combining the questions.

Gameplay: Decoding - Survey - Exposure

1. Decoding: The Commander shuffles the decoders face down and distributes one of them to each player (including the "Alien Decoder"). Then the commander draws the top question card. Nobody is allowed to see who has which decoder.

2. Survey: The commander pushes the question card into his decoder, silently reads the deciphered words and gives the entire group a short and loud answer. Then the commander passes the same card on, to the next player, who does the same. This continues until all players (incl. the secret alien) have given an answer.

3. Exposure: Now, based on the answers, the crew tries to unmask the alien. To do this, everyone votes on the player they believe is the alien in this round.

The points are distributed and a new round starts.

After 10 rounds, the player with the most points is the winner!
