To dupe your entire character, you need 2 players. The player who inventory is to be duped has to take off his helmet and/or face mask so it doesn't get damaged and place it in his inventory. The other player then proceeds to knock the players who's inventory to be duped unconscious. The moment they wake up, the person who went unconscious, has to stand up, them immediately log out. When they log out, their null character in game will crouch then stand back up again. When this happens, at that moment, they stand up.. the player who didn't log out, shoots them in the head. At this exact moment of death, the other logged out player, logs back in immediately.. he then spawn in next to his dead body, with all his gear.. the dead body can be looted, it contains everything the player has in his inventory. There is now an exact copy of the player who wants to dupes, inventory, in the NULL dead body of the ground.
