Sobald ihr Steam startet, sollte automatisch ein Patch für Call of Duty: Black Ops (ab 40,00€ bei kaufen) runtergeladen werden. Das Update verbessert die Performance - speziell bei Zwei-Kern-Prozessoren - und behebt einige allgemeine Absturzursachen. Die Quickmatch-Funktion sollte nun "bessere Partien" heraussuchen und zugleich haben die Entwickler das Spawn-System (Mulitplayer) überarbeitet.
