CheatCodes.com has all the official Call of Duty: Modern Warfare 3 PC cheats to unlock everything. If you know of any that we don't have, please let us know.
All published and official codes as of Friday May 24, 2013 for Call of Duty: Modern Warfare 3 are shown below. We also have this game on PC, Nintendo DS, Xbox 360, PlayStation 3, Wii, and sometimes tricks from other game systems will also work on PC.
When typing in your name, press shift and ^ and then a number. It will delete the symbol you just wrote, and change the color of your username. The colors are:
Once you hit level 20, use the Specialist package.
Make a class, give it hardline and use the Specialist package. It not only gives you extra points at kills 1, 3, 5, and 7 but also helps you complete the perk's challenges AND the Specialist Challenges for each perk.
You are completing the perks and each perk has a Specialist perk challenge to it. For example, if at 1 kill you unlock Assassin, you are completing Assassin Challenges while also completing the Specialist Challenge entitled 'Assassin.'
This equates to a boatload of XP once you start moving through these challenges. Not to mention the 200 XP per kill at kills 1, 3, 5, and 7 every time. You will be hard pressed to find a faster way to gain XP while playing any kill heavy mode.
You get EXTRA points for kills 8, 9, 10 etc. as long as you have all the perks on and have not died so it's like double XP in on itself.
These perks operate in addition to the standard 3 assigned to the custom load out chosen at the beginning of a match.
