Call of Duty Tips & Tricks

Hints
Berlin: MP 40

If you want to get an MP 40 in the final mission, do not take the first one that you see. Wait until you find the second MP 40 and take it. You will get about 500 rounds of ammunition, which should be enough to complete the mission.

Boot Camp: Linejumper

Enable cheats to reach the linejumper. You can exit the same window (but you will just fall to the ground). Using grenades to kill a jumper will stop all the other jumpers.

Brecourt: Easy kills

Toss

Burnville: Running out of men

In the field at the start of the level, charge forward past the three MG42s in the windows and sandbag. This is best done under the easiest difficulty setting. Stand there without shooting anyone, and your men will waste themselves on the 42s. If this is done long enough and with "insane body count", they will stop spawning all together. You can do the same thing almost everywhere else there is a 42 and spawning men.

Chateau: Early truck

If you stay near the wall near the three garage area, you can loop behind the truck. You will see it just sitting there with no one on it. Unfortunately, you cannot blow it up.

Dawnville: Saving Johnson

You can save Johnson by running out with him. You can Faust the Panzer coming up either through the church window; or if you are very brave, by running out quickly and reaching it before it gets to the barrier.

Dawnville: Get back to church comment

If you run to Moody's position before the appointed time, he will tell you to get back to the church

Dawnville: Retreating back to the church

Get a Faust before going to Moody's position. Taking out the tank just when it appears will cause your men to run headlong back to the church. The gate will not come down, and the house and fence will not explode. This often results in them getting slaughtered by the two or three Nazis standing guard.

Dawnville: Shooting Moody's attackers from the church

You can shoot the men assaulting Moody's position from the church window. However, you first have to trigger the event by getting to Moody first, then looping back.

Pathfinder: MG42 window

You can toss a grenade to the side window by the MG42. This useful under the veteran difficulty setting.

Pathfinder: Avoid explosion damage

When you place the charge on the cinder block wall, crouch behind the wall. When it explodes you will not die or lose any health.

POW Camp: Deadly crossfire

On the way back, just before you get to the truck, there are three ways to get back to Foley; the alley closest to you, the alley furthermost from you, and the alley in between. You can play around with the alleys and their triggers by running back to the common areas and going down a different alley. By doing this, your men will get caught in a three way crossfire.

Hidden comment

In Burnville (the second map), when you have to go into the church to knock out the two machine gunners and the antiaircraft fire, do not go to the church. Instead, stay behind the big tomb with a cross on it and throw grenades over the wall to where the two machine gunners and antiaircraft guns would be (the corner of where the walls meet above it). Keep throwing them until someone says "Way to chuck, Private".

Fly through building

Go to the Berlin level. Enable the ufo code. Fly to the other side of the level, to the big building with all the Nazis in it. Fly towards the back-right corner of the building. You will enter a blue glitched area and see the letters "FX" floating in mid-air.

Pathfinder: Mystery weapon exchange

The very first Nazi has his Kar98 leaning against a tree. Normally, he picks up the rifle and shoots at you. However, you can also kill him before he picks up the rifle and it will still lean against the tree. If, however, you charge past him and swap your weapon for the Kar98 against the tree before he reaches for it, he will grab the weapon you left behind, but bring a Kar98 to bear on you. Your original weapon will still be leaning against the tree. Kill

Chateau: Two Moodys and Foleys

Run through the engagement where two Nazi trucks come up and get yourself into the chateau quickly. Moody and Foley will not unspawn. They will guard the chateau entrance with their SMGs. Later, you will have two Moodys and two Foleys.

Boot Camp: Phantom 42

Enable cheats, and force Sgt. Avery off the 42 with grenades. Then, crawl through the obstacle course. The 42 will rise up and aim above all the trainees' heads as if someone was controlling it, but no shots will be fired.

If you want to get an MP 40 in the final mission, do not take the first one that you see. Wait until you find the second MP 40 and take it. You will get about 500 rounds of ammunition, which should be enough to complete the mission.

Boot Camp: Linejumper

Enable cheats to reach the linejumper. You can exit the same window (but you will just fall to the ground). Using grenades to kill a jumper will stop all the other jumpers.
