This expension is a campaign allowing players to participate in an adventure scripted in 5 scenarios which brings, collectively during the game, players to make choices that will tip the story towards Peace or World War.

At the beginning of a game, players open an envelope containing the story, the special rules of the scenario and the extra cards for this scenario. Then, at the end of the game, each player gets different rewards depending on whether he won or lost and according to his own choices during the game (depending on the scenario).

Thus, everyone builds their Heritage over the 5 scenarios. The winner of the campaign will be the one who wins the last scenario.

The campaign provides 6 scenarios in all because there is a branch, depending on the choice of players in scenario 4.

During the campaign and after the campaign, players will unlock cards which can come to enrich the basic game definitively. The Heritage campaigns therefore offer players to participate in a story and gradually unlock a mini-extension to the base game offering a new mechanic, a bit like a Legacy, but totally replayable because there is no alteration of equipment.

The campaign can also be played solo.
