Just noticed. They have a free cam kill cam. How? And why don’t we get it in the regular game?
Would be nice to have a kill cam!! 
Right? Instead of the terrible tracking we get now of whoever killed us through a wall. Would be nice to give more accurate callouts to teammates if you weren’t able to hit your tag button before dying.
They set it up in custom games, you can have a ‘player’ in as spectator.
Hilarious it’s not on by default in matchmaking.
I guess with how broken customs is my friends and I haven’t bothered to dig that deep into the settings but we did recently play a custom game where settings were similar to Halo 3 and I feel like it was even better than the way Infinite plays now.
