Big Mamie campaign breakdown
Intro
She's finally here! At long last, you can earn U.S. Tier VII Premium battleship Massachusetts. The Big Mamie Campaign runs for 6 weeks, and you have 120 milestones to complete in order to unlock her. She isn't the only ship included in this Campaign either! At milestone 40, you can also earn Yahagi, a Japanese Tier IV Premium light cruiser. This time, there are three biweekly Havocs to complete—you have 2 weeks to complete each one. There are no catch-up mechanics, so don't miss a fortnight!
The TL;DR is: Massachusetts & Yahagi, three Havocs in 6 weeks (2 weeks for each Havoc), no catch-up.
Massachusetts is a highly anticipated ship, plus there's Yahagi in the mix, so don't expect this Campaign to be easy!
Let's take a look:
