The single player campaign of Modern Warfare kicks off with the Fog of War mission which has you looking for chemical weapons. In this mission you will infiltrate a military compound and take on waves of enemies in an attempt to capture a supply of gas chemicals.
In this mission you complete the “Nothing but Net” achievement in the game which requires that you take out the machine gun enemy located mid-way through the mission. After making your way into the compound you will find a machine gunner laying down suppressive fire on a door that your team breaches. The enemy will be located off to the left of the train yard area behind a bright blue spotlight. To reach him you’ll need to fight through some enemies. Once you make it to the staircase leading up to the machine gunner simply lob a grenade at him to complete the achievement.
In the video below you can see the exact location of the Nothing But Net Achievement at 07:35. Other than that, the Fog of War mission is fairly straight forward with no other collectibles to find along the way.
