Uncharted 3 Infinite Spawn-How to Easily get Kill Trophies

How to easily get kill trophies e.g Survivor,Reload Master,Side arm e.t.c.. Easy...when you get to this point of chapter 14 "Cruisin' for a Bruisin'" what you need to do is just not kill the armored brute just leave him alone...so if he stays alive he spawns 3 soldiers again n again until you kill him...so all you have to do is not kill the big guy and the soldiers will just keep on spawning from the other side......hope you guys enjoy the video.plz like..sry 4 my english
