"Complete all tasks, deploys, heroic battles, incursions, epic bosses, and challenge modes in a chapter to complete it.
Completing a chapter will grant awesome rewards!"
— S.H.I.E.L.D. Intel
Each chapter has a number of requirements to be completed in order to fully master it. These requirements are:
Mastering all the requirements yields various rewards for the player.
Each Missions, with a couple exceptions, now permanently set the difficulty to the Agent level when the Mission was first played and completed. This means that for example, a Level 100 Agent runs Mission 1 of Season 2 for the first time, the difficulty is permanently set to Level 100 even when the Agent has Leveled up since.
This change does not affect Premium Missions, as their difficulty is still set to the current Agent's Level. Missions that are set to Challenge Mode are also not affected, as the difficulty is set to the current Agent's Level plus 10 Levels.
