Poison Promise is the third downloadable campaign available for purchase through the Journeys in Middle-earth companion app, offering a completely new set of quests and challenges. This campaign uses elements from both the Core Set and the Spreading War expansion, which means you will need both products in order to play. With a branching storyline full of twists and traitors and different endings depending on your choices and actions, you won’t want to miss out on the game’s longest campaign yet! -description from publisher's website
