Pandemic Legacy is a cooperative game where all players must work together to develop cures and prevent disease outbreaks, before 4 diseases contaminate humanity. You will all win or lose together. Can you survive the year and save humanity? Unlike most games, which fully reset every time you play, Pandemic Legacy carries some elements forward from one game to the next. Decisions you make in game 1 will be there in game 2, 3, and every game played with your copy of the game. Different groups will make different decisions and will have a different experience. What results is a game unique to the group that plays it. Sometimes you will write on parts of the game. Sometimes you will put stickers on cards or the board. Sometimes you will even destroy (tear up) a card. These changes are permanent. Also, at the end of each game, the group will make two Game End Upgrades to prepare for future games. You will put stickers on the board, cards, and character. As you play, you will learn about other ways the game will change.
