Armor (Assassin's Creed 2)

You can't. It seems like using the Cheat Engine you can somehow remove the armor, but it's dreary.

In addition to the above, this can be done in Brotherhood and sort of in Revelations, since this is the only way to replay the memory somewhere at the beginning of the game, where the character does not yet have armor. But this is a real hemorrhoid, because you have to play the memory a bunch of times and play with zeros and ones.
