Call of Duty 4: Modern Warfare was the franchise’s first title to focus on modern warfare. Previous to this, all titles had been in the WWII arena. We had to reassure the fans that this would still have the same quality as the previous titles. On top of this, the highly anticipated Halo 3 was also launching during the same period. We had to come out of the gates with a launch trailer that convinced gamers that this was not just as good, but better than before.
In the end, Call of Duty 4: Modern Warfare became the best selling game of 2006, outselling Halo 3. Mission accomplished.
