The October update for Battlefield 1 has arrived. This month's patch is now available on PS4, Xbox One, and PC and primarily makes an assortment of bug fixes and gameplay tweaks to the online shooter.

One of the more notable changes DICE has made to Battlefield 1 is removing the 40-player option for Operations. "Based on continuous feedback from our community and an ongoing effort to ensure successful matchmaking for Operations servers we have disabled the 40-player option," creative director Lars Gustavsson said in a statement on the game's website. "We've determined that by allowing servers to only support 64-player Operations, match joining times are kept at a minimum and the probability of joining an active populated server is drastically increased. Our goal is to unite our players under this fan-favorite mode and consistently provide more instances of matches quicker."
