The Manhattan Affair

Overview
is a limited time event consisting of 5 operations which can be mastered through 3 difficulty levels. They are one-time operations and do not drop from doing jobs. You must complete all 5 operations on the Easy difficulty level before you can start Medium level and so on for the Hard level.

As you complete all 5 operations on one difficulty level you will receive a mastery item and will then be able to redo the operations at the next difficulty level. The timers for these operations start automatically as they become available to you.

Rewards
All operations share the same rewards on all difficulty levels.
