After seeing this screenshot from a few days ago I couldn’t help but notice a couple clips of it in the latest Multiplayer ViDoc.

I took some screenshots of the clips that seemed to showcase this unknown (Vortex) map.
Seeing as how there are vehicles/large open spaces, it looks like this will be a BTB map. Also if you look at the bottom right of some of the images, the game type reads “Infinity Big Team Battle“. Does anyone think this is the Waterworks/Blood Gulch map that Frankie was referring to?
