Hey there guys.
I’ve found an almost full proof way to get perfections in Halo 4. In the video below its explained in slightly more detail but the general principle is that you should search in team doubles and try and vote for dispatch. Watch the video for a better explanation : Easiest Map to Get A perfection in (With Rampage Perfection Gameplay)
Haven’t heard the audio but dude, thats just you playing really well, from watching the gameplay I can’t see how thats going to help anyone get a perfection.
