Tomb Raider: The Angel of Darkness
During play, pause the game and hold L1 + R2 + Down + Triangle. Release those buttons, then quickly press Circle, Up, Square, Triangle, Right, Down. A level skip option should appear at the pause menu.
Money and items respawn, so just find an area that you can safely exit and re-enter, and you can keep collecting whatever is there.
