F.N.G is the first mission you will do in Single Player, it is mainly a Tutorial Level and it suggests what difficulty you play on at the end.
Gaz will talk to you as you come into the room, as you go near the weapon, press the use button to pick it up. Then Gaz will give you your next instruction
You will be told to aim down your sights and hit a high target then a low target, then the game will ask if you want to reverse your controls for up and down, if you are struggling, you may want to do this, you can always do it later in the options if you do not do it then.
This is just to make sure you can shoot from the hip. Just aim up the sights with the targets and fire. They should go down
This is to show a new feature of Call of Duty 4, you can shoot through some surfaces if you have a powerful gun, try it out, the targets are near the middle of the board but keep shooting until they all go down.
This is to test the Auto Assist feature (Xbox 360 and PS3). Try shooting the targets with and without the feature to see which one you prefer, you have 10 seconds to shoot all of the targets. If you don't do this, you will have to do this again until you do. On the PC version there is modified dialogue and you will have to do this unassisted.
Now go back to the table where you got your rifle, you will find a pistol there. Pick it up using the use key.
This is to show you how to switch between the two weapons you can carry, just press the button when Gaz tells you to and listen about when to switch weapons.
Go up to the watermelon and press the melee button to knife it, the bigger your weapon is that you're holding, the longer it will take to use the weapon after knifing.
look at the indicator, go out the door and follow it to where Captain Price is, make sure the yellow blob is in front of you and that the metres away counter is going down.
The CQB test is a test to see how well you will do in the game, it will recommend a difficulty but you are still free to choose any you want. To Start, go to the ladder and look up then go forward, you will climb it, then swap your gun for the MP5 by pressing the use key, then go to the rope and press the use key, do not jump. You will go down the ladder
