Mittels der automatischen Update-Funktion ist ein Patch für Battlefield: Bad Company 2 (ab 14,09€ bei kaufen) auf Version 522175 verfügbar. Mehrere Single- und Multiplayer-Bugs bzw. Absturzursachen werden aus der Welt geschafft.

[NOTE: 522175 is merely a re-packaging of the datafiles from 522174. Therefore, version 522175 reports itself as 522175 in the auto-patcher, but does still say "522174" in the game's splash screen.]
