DICE has announced that Battlefield 3 PC will be updated on December 6, and boy is it a doozy. Clocking in at around 2GB, the client and server update will include a dizzying list of improvements to game balance, as well as fix a number of bugs, but that's not why the patch is so massive.

The 2GB patch will also include "most of the content for Back to Karkand," the game's first expansion pack, included with first-print editions of the game.

Back to Karkand DLC retains a week of exclusivity on PlayStation 3; PC gamers will need to wait until December 13 to play Karkand, in spite of tomorrow's download.

On "Tuesday morning around 8AM GMT next week," and "coincides with an upgrade of many of our central systems which will be down for some hours starting around that time," the Battlelog notes. Older clients and servers will no longer be compatible after the update, meaning that everyone will be prompted to download, once it launches.

Dumping a 2GB patch on everyone isn't typically the preferred course of action, the Battlelog clarifies. "This is not ideal," it says, "so we aim to make potential DLC content in the future as optional downloads."

In addition to much of the Back to Karkand DLC data and the numerous changes listed below, some tweaks are also being made to "after getting a lot of negative feedback from both individuals and the RSP companies." In a nutshell, it's now again "possible to reduce the number of players required to start a round to 1 both in ranked and unranked mode." This seems to be a precursor to another planned change, which is to eventually introduce a "warm-up mode" into online matches. Ostensibly, this would allow players to horse-around on the battlefield with scoring disabled (prior to the match's start). The match itself would begin once the designated player threshold was reached.

The beefy lists of fixes and tweaks included in the December 6-due patch are as follows:

Bugfixes

• Fixed a problem with spawn timer now showing blue border on startup and lost spawn point

• Fixed a problem where player who joined queuing on End of round got spawn screen stuck on screen, but unable to do anything with it untill next round loaded

• Fixed a problem with the Kill camera acting up when suiciding from parachute
