If both players gain 10 influence in a region, then any further moves played in that region will erode the opponent's influence. Tactics has an associated single player campaign and story where the battles are waged against AI opponents. The player begins with three tutorial missions in Spain during which the key mechanics of the game are introduced using specific decks and pauses in the action to illustrate points. After completing the tutorial, the player proceeds to the first location in Italy for the first full real-time battle.
