Is Call of Duty Modern Warfare 2 completely free?

Yes, this pre-installed Build 11843634 package is offered as a free download on this site. However, the original game is a paid product from Infinity Ward and Activision, so consider purchasing it on Steam if you want official multiplayer and updates.

How do I install Call of Duty Modern Warfare 2?
