Your missions are the best way to lead you through the game. They are given to you by the Mission Control Leader in the upper lefthand corner of your screen. She will give you the most urgent missions first. If you cannot complete a mission, then move onto another one.
Completing missions will also give you great rewards. Be sure to tap the mission to see what they are. Don't forget to claim the reward once the mission is complete.
Limited time missions Edit
Limited time missions (ltms) are missions that are only available for finite amounts of time. Contrary to normal missions, they can sometimes offer great rewards and are recommended to complete if possible.
