As we reported last night, DICE said that the update for the Xbox One version of Battlefield 4 would be coming late this week or early next week. For those that have the game, you get an early Christmas present as the update is live now.
One of the biggest problems that this update fixes is the one-hit kill glitch that has plagued the game for awhile. It also fixes a number of crashes that occurred during multiple aspects of the game. The audio drop out glitch that affected multiple maps has been patched as well.
Specific to the Xbox One, they fixed a problem with going online after resuming from suspended mode as well as issues with Xbox One parties. DICE said they are already working on their next patch based on fan feedback too. You can view the full rundown of the elements of the patch here.
