Polar Base is a storytelling game in which the players must find a way to explain how all the members of a polar base met their grisly death, based on the cards they are dealt. Each player is a screenwriter in charge of a different character. Together they narrate the screenplay for a film which unfurls the story in reverse chronological order (à la Memento), scene by scene. After all the players have told a scene each, voting occurs. Then a new round starts. The game ends with each player providing his own version for the final scene. The last round of voting will provide extra points for the best ending. In the advanced variant, players can interfere with the narrating player by imposing some elements to him.
