Well there is a camouflage one but you need Call of Duty Elite-Premium.
there is no cheats sorry
none
there isnt any cheats until u get the intel
Other then some glitches, there are no cheats. You can research on youtube for some glitching tutorials.
as horrible as it is and as great as they where in mw1 there are no cheats in any other call of duty game for the rest of the series
Both Playstation 3 and Xbox 360 are not able to use cheats.
There probably will be but not as many as on the 360 because Infinity Ward doesnt like the PlayStation for some reason.
I think you can get them by finding some hidden enemy intel, at least that's how it works in Call of Duty 4: Modern Warfare.
It came out yesterday but for some reason people cant find it anywhere on the playstation network
There are no official cheats for MW3. However, if you want an Aimbot or invincibility, you will have to hack. Hacking can get you kicked offline though. Hacking is also hard. If you want to hack, search it in Google.
Some not all. Most of them don't.
Yes you can cheat, but, you need to play the game to get cheats. You must find these Intels in the levels. To find them you can get Call of Duty Modern Warfare: Reflex Edition strategy guide. Here are some cool cheats you can have: Infinite Ammo, If you throw a grenade it blows up and 5 or 4 more come out, You can shoot paintballs, and you can do slow-motion.
