I am a firm believer of a massive, beautiful, Utopian scale for Halo 5 and 6. The ability to give you vertigo and overwhelm you is great. While I do not know the limits of the Xbox One gaming console, if the Xbox 360 could make a (watered-down) adaptation of Crysis, Xbox one might be able to withhold the ideas I have made for Halo 5/6.
These ideas are the ones I find the most well done, that is my opinion, but all of these idea's quality are opinions.
I have stuff I want, then stuff I really want, than stuff that I live on. These are the stuff I live on, my master ideas.
Characters
Akiza Tanaka: She acts kind of as a replacement for Miranda Keyes and Cortana. She is obviously Japanese and will usually wield a distinct shotgun painted with the Japanese colors. She is supposed to look less hot and beautiful and serve as more of a badass. You are supposed to grow a deep bond with her also.
Shun 'Kanamee: This is Jul 'Mdama's right hand man. He is a field marshal with a crimson cape and two energy swords. His story is not that deep and he just serves as a boss.
Brutus: The new Chieftain of the Jiralhane who loves Jul's ideals and beliefs. He has a newly forged Fist of Rukt and rules a populus of brutes who supports the new covenant reestablishment.
CNV Commitment to peace: A massive Covenant assault carrier that has twice the size of its out length, width, and height of a standard CSO-Super Carrier. It has many armories and rooms. It is armed with a couple mile wide energy projector, two 5250 mm plasma beams, 350 fuel rod cannons, and many massive shade cannons. It is so big and powerful, it holds 4 carriers!

New levels!
Tokyoscape: This starts at the Japanese UNSC base, leads to a neighborhood, then you get to a big Outskirts styled courtyard, then the massive city, then the bridge tunnel. It will be huge and the decisions are near infinite. It will be a nostalgic mash-up of Outskirts, Metropolis, and Tsavo Highway in one big climax for cities. It will have a scarab battle, multiple bridges, hunters, and the hated but remembered Jackal Snipers.
Climax: FOR HALO 6!!! This mix of Assault on the Control Room, Metropolis, Uprising, The Covenant, and Reclaimer into Michael Bay’s blender will be the largest level EVER. It will start with you crashing into a forerunner observation deck on the Greater Ark. An army of ~200,000 covenant attacks and brings in Wraiths, Hunters, Snipers, Scarabs, and a Harvester! This will have the longest gondola ride in a misty jungle mountain, have a massive scarab and harvester battle in the citadel (3-4 scarabs in the fight), multiple Mammoth rides, controlling a mass driver cannon, Prometheans blasting through TONS of flood, and more!
