With the level 1-2 scanning array, you can scan for 1 side quest a day. Level 3-4 scanning arrays can be used to scan for 2 missions a day. You can scan for 3 in a day if your scanning array is level 5. If you have accomplished all available side quests, you can scan for missions for 20 gems. The reward is based on the difficulty of the side quest.
Campaigns won’t be randomized: they are based on your experience level.
Every scan cost 5 spy drones. 1 spy drone costs 10k gold and elixir.
