Use scope on any gun:
Your binoculars can be used as a scope by using the center of them as the sight.
Ammunition room on "Failse Road":
As the British you will have to clear out a building. When you clear it out, go up to the upstairs area and move to your right. You will find a little room. When you get to the entrance, look to the left to find three KAR98Ks and three MP40s. You can pick those up whenever desired, and they respawn. Collect them if you are low on ammunition, then return there again when you need to restock.
Easy completion of "Night Drop":
When you meet up with the French rebels you'll have the choice of going left to the Flak 88s or going through the house to the right. Go left to the guns and 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 go through if had chosen right. When you go in the house you must defeat a Nazi that is there waiting for you. Kill all the enemies in the house and fall through the burning floor. You will find your allies there waiting for you.
Best gun early on "The Island":
On the second mission, "The Island", there is a man under the second bridge with a FG42 scoped. That gun gets you 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.
Scoped FG42 on "The Mace":
When you reach the part where you must keep the Nazis from the trenches, do not listen to the men. Instead, go to the right and follow the path to find an FG42 scoped leaning on a crate.
Capturing the church on "Saint Lo":
In Chapter 1 (Saint Lo), capture the church by killing all of the Nazi soldiers (while hiding behind walls etc.). It is recommended that you use the Thompson gun in your arsenal. Once all the Nazis in sight are dead, go up to the church and throw two or three smoke bombs in it. After that, throw two grenades into the church while the smoke is still active. Once done, you will be able to go to your destination, capture the church, and be able to move on.
Avoid being seen on Multiplayer mode:
When playing in multiplayer mode, you can avoid being seen by hiding in tall grass. Keep moving back and forth because the enemy can see you with the red hash marks if they happen to aim at you.
Determining your team at auto select on Multiplayer mode:
When you play online, highlight "Auto Select" and there should be the shape of a body.
When sniping, get into a nook, cranny, or other some small place where you can either crouch or go prone. Make sure you have a good view on your targets. Tall grass is also a great idea, as well as areas 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 to pull out your pistol and use your binoculars to spot your target. Your position is much less obvious if you use your binoculars. Although many people will debate this, do not take any more shots than you need to. If possible, take them out in one shot. Do not shoot unless you are sure that you will kill your target without their friends detecting your position.
Getting more ammunition hint:
If you like a particular weapon from your faction, such as the M1 Garand or Bren, use the following trick to get more ammunition. Find a character on your team that isn't unkillable, such as Sgt. Dixon, or Lt. Robiechaud, and melee them. More often than not, the game will not fail the mission, allowing you to pick up the ammunition and continue the fight.
Rapid fire tank hint:
Select the support kit and lay prone next to the tank until you see the "Press X to enter" message. Then, hold LT and enter the tank while LT is held and your tank will rapid fire.
Enter hill on Eder Dam:
On the"Eder Dam" map, select support (recommended) and go to the base on the right side of the bridge (when looking at it from the two story house). Once there, go to the motorcycle on the left side of the base and enter it, but don't turn the handlebars at all. Simply hold B until you are all the way backed up. Exit and you will be under the hill. Stay on the grass and do not go too far back or forward or you will fall off. You can lay down and are able to shoot through the hill.
Pass through wall on Eder Dam:
On the "Eder Dam" map, go to the base on the right side of the bridge (when looking at it from the two story house). Once there, go to the motorcycle on the left side of the base and drive it to the right side of the base, then park parallel to the wall. Exit and you will be on the other side of the wall. You can now shoot through the wall (not the building) Note: The other team can shoot through the wall also.
Look through walls in France:
In France, go into the broken house across the street from the barn and go inside the room closest to the street on the second floor. Climb the side of the house that looks like steps to reach an attic where you can look through the walls. This is a great area to snipe from.
During any mission, when you kill a German soldier, look at his helmet. You will see the new German flag (black, yellow and red), which did not exist during World War II. During that time period,Germany used a red flag with the swastika on it.
Enter invisible building outline:
Note: This only works when playing an online match. Find a game on Eder Dam online and go to where all the sheds are located and the Allies regularly start CTF games. There will also be a jeep respawn and boxes out in front of the sheds. Go down to the edge of the map where there should be a broken bridge and more sheds, then take the motorcycle that is near a fence and the broken bridge. Get onto the motorcycle in the driver's side and drive up to the part of the shed on the left when facing down the hill. After that, drive into that open part of shed. Accelerate while turning into the top left corner. Continue accelerating and turning, but while doing this exit the vehicle. If done correctly, you should have entered a see-through chamber which is not meant to be entered. You can see 360 degrees around and it should be clear. Note: There is also a window frame here and if you walk up to it until you cannot continue further, you should be pointing the barrel of your gun out and can shoot at enemies walking by. They won't be able to see you through the solid outside. It is also recommended that you take in either a support or anti-armor class to resupply yourself with ammo. You cannot exit the chamber and must either respawn or kill yourself to exit This also works in many other nooks and corners in the online games, but only in the maps that have motorcycles in them.
Sniping position on Poisson:
On the Poisson map, there is a barn or house behind a Nazi Tiger Tank spawn. This part of the map is the part where the Nazis usually respawn. Go in and climb the ladder, then walk over to the window in the front. To your left should be some boxes. Back up, get prone, and crawl up to the corner on the left side of the boxes. Crawl until you cannot move further. Then, stand up. If done correctly, you should be apparently on top of the roof. Although you cannot move, you will have a good sniping position. If you prone again you will be back inside the house. You will also have an excellent view on the little town area and the road to the right that leads up to the house that is next to the other Tiger spawn point.
Walk through roof on Poisson:
Start 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, then 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 and can walk through the roof, giving you a good view of the area around the fountain.
