Mission Event: Get A Grip

 The new mission event has hit the feeds, and this is one that even I'm interested in!
 As it says on your new homepage banner about the mission, the grand prize is "limited time secret district."

We know this much:

"Secret Districts are job tiers which will occasionally appear in Brazil for a limited time. While one is available, you'll be able to access it from a "Secret Districts" button on the Job page next to the normal Districts. These new jobs will drop exclusive new loot items, so get started as soon as you can!"

Kinda sounds like these will be an ongoing part of missions now?
I'm off to explore - I'm sure we'll have much more to say on the subject!
