In the level "Blood Brothers" when Yuri has his flashback, the first scene is in Pripyat, Ukraine. This is what the ultranationalists saw on the ground in a Call of Duty Modern Warfare level. The next scene is at the Al- Asad safehouse. Helicopters can be seen coming from the distance. Again, in Modern Warfare, the player is aboard one of these helicopters. And at the scene where Yuri crawls into the terminal in "No Russian" (Modern Warfare 2), he attempts to kill Makarov. If the player goes to the level in Modern Warfare 2 and turns around, Yuri can not be seen struggling to kill Makarov.
