This mod utilizes Texmod. UPDATE. Texmod no longer works With the AC:Brotherhood uplay launcher via Steam.. So looks like you're going to need to get the cracked version of brotherhood, just do me a favor and support the company by BUYING THE GAME if you can.
Just read the Read me file in the rar file and look at the before and after pictures in it as well so you understand.
If you truly want this to work as seen in pictures a new game is recommended. Here is why. You can NOT purchase any armor at all rather than spaulders...
