Call of Duty 3

Create an online game in Poisson. Near the barn, next to one of the truck respawns, there is a flaming building. Get on the second floor by climbing the stairs. When you are up the stairs, turn around and you will see a small side room. Go in the room. The wall is partially destroyed and on fire. Notice that on the wall you can climb to the third floor. Slowly and carefully get on the edge of the second floor and jump up on the wall. Jump again, then once again. You can now access the third floor of the flaming building. You can walk through the roof, giving you a good view of the area around the fountain.

In Chapter 1 (Saint Lo), to capture the church you must kill all of the Nazi soldiers (while hiding behind walls). It is best to use the Thompson gun in your arsenal. Once you have killed all of the Nazis in sight, go up to the church and throw two or three smoke bombs in it. After that, throw two grenades in the church while the smoke is still active. Once you have done that, you will be able to go to your destination, capture the church, and be able to move on.

When sniping, get into a nook or cranny or other some small place where you can either crouch or go prone. You should also try to get a good view on your targets. Tall grass is also a great idea, or even better, an area where people will not realize you are there (for example, camping on the enemy's spawn point). When sniping on a very tricky target, or if you do not want to be seen, try your best to pull out your pistol and use your binoculars to spot your target. It is interesting how much less obvious your position is if you use your binoculars. Although many people will debate this, do not take any more shots than you need to. If possible, try to take them out in one shot. Do not shoot unless you are sure that you can kill them without one of their friends recognizing your position.

On the second mission, The Island, there will be a man under the second bridge with a FG42 scoped. That gun will get more ammunition every time you kill someone. The gun starts with 96 ammo remaining and you can kill about 150 people with it (not including melee). After completing that mission you will have that gun on the third mission, but you must save the gun through the third mission to get it in the fourth mission and so on.

When you get to the part where you must keep the Nazis from the trenches, do not listen to the men. Go to the right and follow the path. You will find an FG42 scoped leaning on a crate.
