Hi I was wondering that this part can be a new capture zone. It even have a good possition to put the capture marker.
This could be the zone
And here could be the marker.

This other zone could have something like a "Precious cargo" that you need to take and leave at a special position on your base. When the cargo go to the base it will be reseted or something.
Maybe the zone could be all of this, but maybe will be cool if it got something mapped like a labyrinth to make it harder to get.
