Gameplay has been changed from previous versions for Pro Evolution Soccer 2009, with key additions to the Teamvision system, tactics changing according to situation, off-the-ball fluency, and AI recognizing strategies that works accumulating data on an ongoing basis within Master League and League modes. Another new addition is the readjustments for ball movements, with new air resistance calculations for the trajectory of the ball. There are also new friction routines to affect ball movement in terms of ground conditions, backspin routines are calculated so that ball slows accordingly, and the bounce of the ball can be used more effectively: players can flick the ball up to tee a shot, or to lift it over a defender's trailing leg. If a player has the ability, they will be able to perform skilful turns. PES 2009 also features a new game mode called 'Become A Legend', much like 'Be a Pro' from the EA Sports FIFA Series. This mode was originally only in the Japanese versions by the name of Fantasista, it was released as a special edition for J-League Winning Eleven 2007 Club Championship.
