5. The first-ever "exclusive raid"
Originally, the game's code led us to believe that a special Exclusive Raid Pass and an invitation would be needed to participate in Legendary Raids. It turns out that this new pass was for private Raids.
The first of these private Raids was spotted in the American state of Michigan this week. A Redditor posted this picture on The Silph Road. It is unclear whether this was a test or an active feature.
