What's new in FIFA 12? Building on the success of recent years, FIFA 12 introduces three main developments: precision dribbling, tactical defending and the player impact engine. These all - and especially the latter of the three - have a major impact on the gaming experience. What does this mean? The impact engine has arguably the greatest impact on gameplay, and it really changes the dynamics of tackling and contact in the game. FIFA 12's impact engine makes tackles look and feel much more realistic, and will no doubt result in more player injuries!
