Where is Multiplayer Player Outline?

They announced and showed off the feature of having an outline around enemy players for better visibility. This was one of my most anticipated features because I have a huge problem with seeing players against the environment. Where is it? If it’s in there how do I turn it on.

it is in theater

Ugh so it’s not in the actual game…wow

I wish that was in game as it would really help old, almost blind guys like me.,

Ya, I complained so much in the feedback forms about the visuals. It is really hard to see players against the visuals, which hasn’t been a problem until Halo 4 and it is disappointing. I was really excited when I heard this, but now I’m pretty upset its not in there.
