Night Drop mission: Easy completion

When you meet up with the French rebels you will have a choice to go left to the Flak 88s or go through the house to
the right. Go left to the guns. Kill all the Nazis around the gun and in the ditch leading to the next gun. Then, blow up the 88 and move on to the rest of the guns. After you blow up all the guns you will reach the house that you would have had to take if you went right. When you go in the house you must defeat a Nazi that is standing there waiting for you. Kill all the enemies in the house and fall through the burning floor. You will see you allies there waiting for you.

The Island mission: Best gun early

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.

The Mace mission: Scoped FG42

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.

Best Cheat

The best gun for any level on this games is an MP40. Wherever it say 'click and hold X to swap for an MP40' always click on it.

Hold your breath

While playing as a sniper in multiplayer mode, you can steady yourself by holding your breath. To make your character do this, look into your scope and then hold down the L3 button (which is done by pressing down the left analog stick). This will only last a few seconds, naturally, but it will help you shoot more accurately.
