Battlefield 4 developer DICE has “strongly” advised players to download the day one update to help improve the multiplayer.
“”This Battlefield 4 update contains improvements to the multiplayer portions of the game,” the developer explains. “We strongly advise you download it.”
There’s no explanation as to why this update is needed so urgently or what it does to the multiplayer but given DICE’s warning, it might be best to download the 119.21 MB update which is available for players to download now.
