COD4 Instant Rank 55 : FPS / MMORPG / RTS Discussion

In Call of Duty 4 you have to unlock weapons, weapon attachments, camouflage, and challenges. Here is a quick and easy way around all that because all of the data is stored client-side. Its really quite simple, just follow the directions below and enjoy. I have done this now a couple times for my friends and myself and it has made game play more enjoyable.

1. Download this mpdata file.
mpdata.txt

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.

You now should have a level 55 and everything should be unlocked for your use
I heard word that with the release of patch 1.4 that it resets this everytime you log on (It works up to newest version), i have not personally had this problem but you can keep redoing this if you do.

Nice
