NHL 12 is now loaded with even more bone-crunching power according to the new feature trailer revealed for the game.  They have a new full-contact physics engine that packs an extra punch to shatter the glass and knock opponents out of the arena.  Goalies are now live so you can effectively crash the crease and knock the net off its mooring.  Perhaps the best new feature can be summed up in two words:  Goalie fights!  Not since medieval times have two heavily armored combatants engaged in a melee this brutal.  Check out NHL 12 when it glides onto shelves in September.  [via IGN]
