Since none of us know what were fighting yet i hope that the chief lands on the planet in the night time in the middle of a forest. This would give it a scary effect because you wouldnt be able to see your enemy fully until you killed one so they could be sneaking up on you throughout the whole first mission. However this would require 343 not to release any Campaign gameplay before launch which i highly doubt they will.
You’re about ~2-3 years late to be making this suggestion. Just sayin’ 
I would rather like a mysterious feeling in Halo 4. I want 343 to go back to the feeling of when I first played Halo and was filled with such wonder and mystery that someone could create such wonderful things with their mind.

I know but they could do what Bungie did with Halo CE when they introduced the flood.
