Unique ideas for the halo universe

Since I was 12 in 2001 I’ve been thinking of many ideas pertaining to the halo universe whether it was weapons, enemies, vehicles, species, religions, planets, story lines. Anything I could think of to expand this world I’ve loved for almost 20 years. Please leave any ideas here for discussion.

There’s a part in Halo 4 where John tells Cortana that if he can get her to Halsey, they can fix her. And she tells him that if they do, it won’t be really her that they end up with. And that they may even pair him with another Cortana model.
I’ve always loved this idea, mostly because I don’t believe (or want to believe) that Reclaimer Cortana is Cortana from Halo 1-4. I think she’s a fragment and the part of Cortana that formed a relationship with John really did die in Halo 4.

So what if John was introduced to another Cortana model to stop Reclaimer Cortana? I think it would be really fascinating to see how he deals with someone who looks and sounds exactly like the Cortana he cared about, but isn’t her. And on Neo Cortana’s part, how she would try to partner up with John and gain his trust (so they can save the universe) after he has closed himself off from any emotional attachment, probably more than he ever has before.

just a thought.

A game where you play as a member of a super elite team of sangheili warriors during the human-covenant war, the humans are the enemies, and you are task with carrying out the most dangerous suicide missions the covenant has to offer.

I wouldn’t mind a Squad based game, where you can order your team to properly take cover, provide suppressing fire and basically be like Tom Clancy game with Halo Spartans, ODST’s and Marines.

I like the idea of being an Elite during the human-covenant war!

Love that idea!
