It was a long story that I don't remember the reason for. Hopefully we can get back on metacritic in the future. 

Forerunner Trilogy is awesome, I wish they made an RPG during that era.

Both Usze 'Taham and N'tho Sraom are in Hunters in the Dark and looking awesome, also makes me hopeful 343 has more plans with them, I want to see more of Arbiter's friends.

Then there's Rtas Vadum and Tul Juran in Shadow of Intent.

I'd love to see them all in a mainline Halo game again one day - Blue Team, Team Arbiter and Red Team together would be the most hype team up in the history of Halo Now I want to see Thel, Usze, N'tho, Rtas and Tul vs Atriox.

Yeah, so it would also make sense to bring Spirit of Fire into it too, Infinity can't take on the entire galaxy of angry AIs alone.

My prediction is that Infinity will be destroyed early on in Infinite too, I think Infinity is likely the cause of that huge hole in the Halo ring, makes sense with the marines scattered across the ring too, unless Chief went on a random solo journey and left Infinity to go explore a ring which also had stranded marines and a random hole in it.

Would be hype though, if Infinity is destroyed, we get stranded on the ring, regroup with everyone and send out a distress signal, Spirit of Fire receive it and come to rescue Chief + Infinity Crew, Chief sees Red Team emerge from the ship (Reunion time) but Atriox follows Spirit of Fire and that's how we get Atriox into the game too.
