"There are six categories of weapons. There are your Shotguns (great for blasting enemies from up close), SMGs (made for short range rapid-fire), LMGs (amazing at tearing things apart from medium range), Semi Autos (balanced and powerful), Sidearms (great in a pinch), and Sniper Rifles (which do exactly what you think)."
"You can even tell when your magazine is running out of ammo now - your firing sound slightly changes when your ammo is low."
"Weapon customization is more focused.
We definitely want to allow you to customize your weapons in Battlefield 1, but we also heard your feedback that we should try to find a way to do this without adding hundreds of additional attachments. That's why Battlefield 1 utilizes pre-set Loadouts for each weapon - you're still able to customize your weapons to make sure they work with your playstyle, but in a more focused way."
