GamesIndustry.biz - Duke Nukem Forever physics surpass Half-Life 2:
"In a short but hugely impressive real-time demo, a room is almost completely demolished using a weapon that fires tennis-ball sized projectiles. In the first section of the demo, glass panels shatter realistically and fragile boxes full of objects suspended from the ceiling are smashed, leaving jagged corners hanging on ropes while the contents smash to the floor."
