(adsbygoogle = window.adsbygoogle || []).push({}); First of all Codtool or modio do not mod online multi-player play lists, only mods the campaign and co-op.

YOU WILL NEED AN DATA TRANSFER KIT OR CABLE. (you can get the cable of Microsoft for free by phoning up and saying you have bought a 120gHD and you need to transfer you old stuff of your 20gbHD)

Now you have the stuff needed start up a game and save and quit on the first check point. put your game save on your pc (laptop) through the transfer kit. now open up the codtool or modio (another program for modding).

when you open the save up you have options to choose from e.g infinite ammo, low grav, super speed and jump, red dot. once you have chose the mods you want you will need to click on resign do not forget or it wont work. Now when you do this when you start cod up you can resume game and all the mods you chose will be applied. To play the MODS ON ZOMBIE MODE CO-OP apply the hacks you want to the last level of WaW (DOWNFALL I THINK) play all the way through this mission without dieing and watch the end creditsALL THE WAY THROUGH. and zombies will auto load. you can now quit the single player zombie. and host a private co-op match with the mods on with your friends. BE CAREFUL BECAUSE THE MODS SPREAD, ITS CONTAGIOUS!!!! by that i mean it could spread through zombie mode and all co-op game types like the super speed in MP.

HOPE THIS HELPS YOU

No, it cant spread

I agree with Lost sorry dude i dont reckon it can spread either

I know it can spread. from private atch to privte match, if i host then play a match, some one leaves and hosts there own. the game speed is faster, only spread if u use codtool, not modio. and dont tell me it doesnt spread. you do it host your own and invite friends, make them leave and try it and ill bet you my account that it work. dont come out with stupid comments that are not true.
