Hey TTG,
This is My 1st tutorial so i thaught id make it short and sweet.

This is a Tutorial on how to use modded zombie .gpd files OFFLINNE after tha latest patch.

Ok so 1st you want to download the modded .gpd [Easy to find on TTG] and save it to your desktop.

Then open USB-Xtaf Explorer and extract your profile to your desktop. [Have account on USB before doing this]

Open up modio and then drag your account off your desktop into Modio. Then Go to File Content [Where the games are]

Find your 41560855.gpd and RIGHT click/ Replace. Then find the modded gamesave to replace it with [MUST be also called 41560855.gpd or will NOT work]

Go back to file settings and click rehash and resign.

On USB Explorer delete the old profile and inject the modded one.

Then While On xbox 360 dashboard. Go to SystemSettings/Memory/Press Y on the d-pad and clear system Cache. This clears all patches.

When it offers you an update press Decline and you will have the modded zombies.

If done wrong then repeat the above process and make sure everything is right

Thanks for reading TTG
