Call of Duty 4 makes you unlock weapons, weapon attachments and mods, camouflage, and challenges. Well there is a way around that because all of the data is stored client-side. To unlock all weapons for Call of Duty 4 multiplayer so that you don’t have to level up follow these easy instructions.

1. Download this mpdata file.

2. Go to Start -> Run-> Type regedit -> Hit Enter.

3. Go to HKEY_LOCAL_MACHINE -> Software -> Activision -> Call of Duty 4

4. Double-click codkey

5. Save the key in notepad

6. Replace the key with: DL2J8PY44Q22GE4888D2

7. Press OK and close regedit.

8. Navigate to your Call of Duty 4 profile folder (typically “C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\players\profiles\your_user_name”)

9. Back-up and then remove all the files in your user name folder.

10. Place the mpdata file you downloaded in your user name folder

11. Open the COD4 MP game and check your rank. You should now be level 55 with all challenges, guns, and every camouflage unlocked!

12. Finally, in the game go to Options -> Multiplayer Options -> Key Code and type your original cd key you have saved in notepad.

There you go, you now have everything unlocked. Enjoy.

pb might complain as they recently cod4/iw updated with a patch to 1.1 which sorta fixed this, but it still works for me.

I was doing this before

you open your game
you check out how much XP you need to advance
you write the amount - 8 at this offset
iw3mp.exe+C7E9E68
you join a server
you kill somebody
boom promoted.

EDIT
iw3mp.exe+C7E9F34 are points till next advance

Just to toss this in, if you can find an editor that will open the mpdata file, you would then be able to edit the cdkey in this file. Two advantages to this, no registry editing and also you get to use your original cd key. What type of file extension is this mpdata file, I don't have the pc version.

Can you get to 55 on lvl 10 prestige by a hack, to prove the hidden perks?

Don't think so because PC version doesn't have prestige mod.


Yes yes.After using this method go to you're MP settings and change the key to you're original one and it will still work.

It won't (1.3 version).
Game checks your profile each time you turn on game, so you will have to do all those steps each time you want play, each day.
Damn, its most stupid profile protection ive ever seen.
