It's likely going to be an event that'll be released in the future.

Near or far, I don't really know.

think i seen that event in china and taiwan aswell, not sure on germany or brazil, but what i do know is u pair up with other 2 people, fight and hold some lands around the map i believe, now idk if it's group wise or you can pair up with anybody, idk if it's level range to a certain point or not, or power wise, but i do believe it's sorta like strategy based like fight a other 3 people, conquer the land they're in, and hold it i think.

You pretty much described a "capture the flag" type of game. That event exists with the original world map as the battlefield. One of the China YouTubers covered it once.
