How do you get the question mark armor on lost planet 2

it is defiantly not a cant, as said a previous answer, i too myself seek the question mark skin, i see many with it, but when i ask how the acquired it the simply don't reply or refuse to share, this points out that they may have cheated or hacked their x box or lost planet 2 game, i am not certain that this is a hack, as so many people have done it, it is still a possibility, the armour also has a special feature as it may disguise the player as a half activated enemy data post, and once prey has approached they strike, commonly with a gun-sword SP.
