How can I unlock Campaign Missions?
Campaign Missions are special quests with a storyline.
In order to unlock Campaign Missions, you must attack or defend increasingly tougher Positions. As you go up through Position Levels, you can get new Campaign Missions.
Each Mission has two sides - one that demands Defensive forces, and one that demands Offensive. A full list of the Campaign Missions - along with the levels of the Positions required to unlock them - can be found in the Missions tab in the Oracle.
By successfully completing these Campaign Missions, you will get new Units for your army, earn Glory Points, and unlock new stories.
