DICE a mis en ligne une importante mise à jour pour Battlefield : Bad Company 2 sur PC. Celle-ci corrige pas mal de bugs et rééquilibre quelques armes. Cela s'effectue directement par Steam, par l'Updater du jeu ou manuellement par ici.

La liste complète des changements :

- All Weapons Bronze Insignia requiring an unobtainable bronze star for the tracer dart – requirement removed.
- Improved Hit registration made through several fixes and some of the hitboxes themselves have been changed. This will increase the accuracy of guns.
- Blue box chat window removed
- The 2 second immunity when spawning/being revived will now be immediately removed either by firing, zooming, or any movement (move, crouch, jump). A Spawning Player can still orient passively in the Game World..
- 3D vision fixed.
- Fixed slug shotgun zoom crosshair on PC so they better represent the long range accuracy. Crosshairs now close more on PC, similar to consoles.
- Reduced slug shotgun hip accuracy to require zooming for consistent long range accuracy. Hip accuracy is now on par with the semi automatic weapons.
- Fixed a bug on PC where the G3 would do less damage than intended.
- Fixed VADS turning sensitivity on PC so it performs like the ZU23.
- Reduced VADS push back and damage to balance it with the ZU23.
- Fixed a bug where vehicle countermeasures would fail to remove tracer darts at high speed.
- Reduced the reload time for vehicle countermeasures.
- Slightly increased the AT4's damage vs armor to emphasize its anti vehicle role while keeping it balanced vs armor.
- Increased the AT4’s top speed and acceleration so users spend less time exposed when firing.
- Increased the AT4's splash damage so it competes with other AT weapons vs infantry. The AT4 still has the least splash damage of all AT weapons.
- Reduced the splash damage of the Carl Gustav to bring it in line with other explosive weapons. The Carl Gustav still has the most splash damage of all AT weapons.
- Increased the 1 shot kill range of the M95 body shot to counter its lower rate of fire.
- Fixed a bug with the SVU that gave it better close range damage than other semi auto weapons.
- Reduced all weapon damage to the MCOM by 50%.
- Fixed an C4 vs MCOM exploit on Atacama Desert.
- Fixed a bug with FOV when aiming the M1911.
- Lowered the close range damage of the AN94 to highlight its long range role.
- Increased the accuracy of the F2000 on the move to highlight its role as a mobile AR.
- Increased the close range damage of the shotguns to give them a greater advantage vs slugs.
- Slightly lowered the damage of the M60 to balance its accuracy advantage vs other LMG's.
- Slightly lowered the damage of the MG3 at close range to balance it with other high rate of fire weapons.
- Slightly increased the damage of the UH60.
