BBKDragoon an awesome YouTuber, and all around good dude, took these screenshots from the trailer. As you can see a ton of information to take in.
Tons of cool stuff to look at and dig deeper in. Again, this would be really interesting to play and experience. A PC Halo could open the way to mods and a customizable experience for each different audience. Many props to BBKDragoon for capturing these!
