Does anyone know how to get the Egg Hunter badge or the CLASSIFIED badge?
I can’t find much information on either of the two.
The Easter Egg badge was given out to those what found or helped to find Easter Eggs in Halo 4. I imagine they will bring that back for Halo 5.
The Classified medal was given to those who part in a section of the Halo 4 ARG - Operation Little King for reaching 1million WarGames as a community. Again I can see them bringing that one back at some point 
It kinda sucks that some badges can’t ever be obtained again, but I suppose that’s how it goes.
