Battlefield 3 will briefly go offline for maintenance between 8am and 9:30am BST / 9am and 10:30am while the patch deploys.
It was released yesterday on PS3 and introduced a number of gameplay tweaks and balancing, as well as new "rent a server" functionality for consoles. Have a look at the full list of changes here.
DICE still hasn't provided a timeframe for when Xbox 360 players can expect to get the patch.
Yesterday, BF3 executive producer Patrick Bach blamed "frustrating" console certification processes for delaying PC updates.
