|Trophy: Rub One Out|
Rub One Out is a bronze trophy in Uncharted: Golden Abyss.
Throughout the game, you will have the option to do rubbings. These are when you rub the PlayStation Vita's touch screen to get the image to appear on the paper. A few are story related. If you're diligent in getting them all, the trophy will be unlocked after completing the final rubbing in Chapter 31.
