Full walkthrough of the PC game "Call of Duty 4: Modern Warfare 1" (released in 2007) on the hardest game difficulty (Veteran), Act 2: Mission 3 - One Shot, One Kill. The game was played by me with flawless free flow completion of the missions. All the scenario scenes and dialogues were included in the video, from the intro of the game till the credits at the end, hence the watchers can understand the storyline of the game. Enemy Intel locations are shown in each mission. Highest values in graphic options were selected to produce the maximum from the game. Enjoy watching\rating\commenting the video. Have a nice day.
