It was way way better than the first I thought, I wish it wasn't Lekgolo worms though, was hoping we'd be encountering flood forms. It's neat how the story of the Covenant in the past month has gotten 10x more attention with Broken Circle, the Terminals, and now seeing things shown in there applied to Nightfall.

I also feel there is much more interesting things that can be done on the destroyed Halo ring other than "hunt down rare element", namely the unknown ship from the terminals. But maybe that will still happen.
