Create a shortcut and edit the properties of it and add this after all the other stuff: ''+set monkeytoy 0 +set sv_cheats 1'' (without the quotes)

Start the game and press the tilde sign (~) to open the console.

Note: If after you type one of these codes in the console it tells you that ''sv_cheats are read only'', then try typing this into the console: setrandom sv_cheats 1

Enter some of these commands:

When in a Single Player game bring down the console with the key above ''TAB'', and type the following to play any map you want.

Create a shortcut to the ''CoDSP.exe'' file located in the Call Of Duty program files. Right click on the shortcut and go to properties. Go to where it says ''Target'' and add the following onto the end of the existing link:
+set thereisacow 1337 +set developer 1 +set sv_cheats 1 +set monkeytoy 0

So the link should now say something like:
''C:\Program Files\Call of Duty\CoDSP.exe'' +set thereisacow 1337 +set developer 1 +set sv_cheats 1 +set monkeytoy 1

Next go into the game and bring down the console by pushing the button above ''TAB'', then enter the code from below for the desired effect.

NOTE: Some codes apparently crash the game. All of these codes worked fine for me when I tested them, so make sure you do everything correctly and they should work for you too.

The following codes only work if you have set up the Console Cheats shortcut. While in game, press the tilde key (~) to open up the console to enter the cheats . Once entered you should get a message (also in the console) stating that the setting has been changed to whatever the variable was that you entered.

Note: You may want to put GODmode on when using low gravity if you dont want to die as soon as you land from your 500 foot jump..

At the command prompt, enter "give (mind the space) followed by any of the below strings to summon ammunition for that weapon. Note that the weapon itself will not be spawned, thus these are only useful if you already have the weapon itself. Handy if you come across a gun you love but can't find much ammo for it.

A word of warning: the game only caches certain weapons for each mission. If you attempt to summon a weapon that wasn't pre-cached, the game will kick you to the main screen. To be completely safe, only summon weapons that you currently have equipped.

Not listed is the "panzerfaust" string. Like I said, the weapon itself won't be spawned, so it's of no use due to the weapon's one-shot nature. Also not listed (because I ran out of fields) is the German grenade, string "stielhandgranate."

Only works in single-player maps with Panzerfausts. May not work in later patches. Make sure you have a full inventory. If one of your primary rifles are low on ammunition, exchange your rifle with a panzerfaust. Shoot the panzerfaust at any direction and pick up your rifle. You will find your rifle ammo increased. Note : Don't do this cheat if you have a full or near-full ammunition. You may find yourself have lesser ammo.
