In the globe-trotting adventure "Uncharted: Drake's Fortune" for the PlayStation 3, you can change the appearance of the character you play, Drake, by donning special costumes. You unlock most costumes by purchasing them with points earned when you kill enemies or collect treasures. To unlock Drake's baseball shirt costume, though, you need to enter a cheat code in the Rewards menu. After you enter the code and complete the game at least once, you can have Drake wear the baseball shirt at any time.
Select "Rewards," and then select "Costumes." Scroll down to the locked Baseball Shirt Drake costume.
Press "Left," "Down," "Right," "Up," "Triangle," "R1," "L1" and "Square." The Baseball Shirt Drake costume unlocks.
Highlight the Baseball Shirt Drake costume and press "X" to equip it.
