Missions, formerly known as Achievements, offer the player various rewards upon the completion of certain tasks and requirements. Missions can be found by tapping the Menu button, below Medal Exchange and above Encyclopedia. Completed Missions may pop up at the upper-right side of the Lobby screen (alongside Guild Invitations, Expedition Limimin, Allot Gear Cost, and Present Box), and can be tapped to claim the available rewards.
Missions are divided into four sections: Special Missions, Schedule Missions (which contains Daily and Weekly Missions), Guild Missions, and Trophy Missions.
