Battlefield 1 will be throwing dynamic weather at you no matter which map you are playing

Adapt on the fly without modern technology

Over the last console generation or so, shooter fans have gotten used to modern and futuristic games that provide such conveniences as GPS and infrared, which in some respects have taken away the necessity of learning the ins and outs of every map in a given game. That won't be the case in Battlefield 1. 

In an all new developer blog, DICE has laid out how the weather will play a factor into potentially every single multiplayer match you ever play in Battlefield 1 as well as how the developers are trying to capture the essence of war as it was fought back then as opposed to now (or in the future). Here's an excerpt:

"All multiplayer maps in Battlefield 1 have dynamic weather that can occur as part of a larger immersion ecosystem. Unlike the game's destructible environments, weather is an outside factor that you can’t control. Things can shift in small ways (like the sun peeking out of the clouds and turning an overcast map into a sunny one) but there are larger changes that can happen that will nudge you to adjust how you play.
 
Dense fog, for instance, limits your vision. This makes it harder for snipers to be effective from afar and changes the spotting distance. With heavy fog, an open map can turn into a melee, close-quarter experience for a limited time. People will need to pull out their bayonets, equip themselves with shotguns, and get ready for more intimate affairs until the fog dissipates."
This isn't to say that the weather will force players to only fight one way. DICE assures that we will still be able to challenge the weather, and skillful players may even find a way to use it to their advantage. In maps like the Sanai Desert, which gets hit by sandstorms, DICE says that while the storm density can make flying difficult, if you're able to compensate for the harsher conditions, you can use the storm's low visibility as an advantage.
 
Just try not to crash.
 

Battlefield 1 had a very successful presence at Gamescom 2016 this week, taking home the award for Best Action Game. The game also dropped a brand new trailer at the show this week and revealed the game's 'Squads' gameplay in a livestream
