Forged Halo 5 Guardians Beta Map?

This is not spam what so ever. It does not contain any spoiler of any kind.

I was certain i have seen this map being posted either on a Headline or Blog on here. Not sure if it was Bravo or BS Angel who stated that someone had already made the Halo 5 Guardians Beta map seen from the Trailer that was shown at E3. If someone else has seen this map could you direct me to it.

Halo 5 Guardians trailer is not a spoiler because its already view able by the public.
