This is just a heads-up that the Nivelle Nights DLC map will free for all Battlefield 1 players in the next few days. It was previously exclusive to Premium Pass and They Shall Not Pass owners.
Starting early November, you can tackle the muddy battlefields around Malmaison and Soupir as the French or German army. Make good use of the moon, the searchlights, and the artillery lighting up the dark night skies.
