PES 2012's is primarily a refinement of PES 2011, with fewer big changes than the previous versions but many smaller improvements and changes in areas such as artificial intelligence, speed, animation, and physic's but it looks stunning on are android devices.
Refereeing has been improved and includes a full implementation of the advantage rule, with the referee pulling back play for bookings after the ball goes out of play. The "catch-up bug", where defenders would catch dribbling attackers too easily, regardless of the attacker's pace, will be addressed. Gameplay is more fluid, with better response when controlling the ball, and goalkeepers have been improved with new animations and generally more reliable goalkeeping performances. Artificial intelligence has been improved over previous PES games, for example AI players will play more thoughtfully when defending rather than simply applying pressure, and AI teammates will make more intelligent movement decisions. Like previous versions of the game, it will be exclusively licensed by UEFA to contain the UEFA Champions League, UEFA Europa League and UEFA Super Cup competitions along with a license from CONMEBOL to feature the Copa Santander Libertadores. Referees' governing UEFA Champions League, UEFA Europa League and UEFA Super Cup matches will wear the official UEFA Champions League uniforms, which is a first for the series.
