In 2008, Pandemic was released, introducing players to Matt Leacock’s intricate, cooperative gameplay system. Since then, many other games, both standalone and expansions, have spawned from the base Pandemic. Many of these titles are built within the Pandemic universe, focusing on science and medical threats and solutions to push the game along. However, a few were designed outside of that for the Pandemic Survival competition, an organized play format. The games that came out of this tournament style format went to not only different time periods, but also explored different threats and stories, creating the beginnings of the Pandemic System.
