EA Dice will reveal a new desert map for Battlefield 1 at GamesCom 2016 next week. The developer has confirmed the reveal on the game's website.
"On August 16 at 12PM PT/9PM CEST, a new Battlefield Squads livestream will show off a new map filled with Only in Battlefield gameplay. There's a new trailer coming soon, too, with a trainload of new information about Battlefield 1." the announcement reads.
The new map is most likely similar to the desert map that was briefly shown in the game's announcement trailer. The map has players battle it out onfoot, in vehicles, in planes and even on horses.
