My wishlist is:
* Content at launch. Map packs that are made from scratch as DLC, armor and skins could also be in the DLCs but not playlists like infection etc.
* Campaign with flood, brutes, scarabs and more Chief. Let the revive and command option stay with Arbiter on the fireteam. HCE/H2/H3 level design and HCE/H2 music with a H2/H3/H4 storytelling. Return of flashlight and nightvision like in HCE.
* Armor abilites, spartan abilites and equipment items. I would especially love promethean vision, jetpack, evade, regenerator, gravity lift, shield drainer, hologram, armor lock, invincibility, tripmine, bubbleshield & autosentry to return.
* Return of grenades, new grenades added like smoke and stun grenade + nade cooking.
* Like a destiny kinda lobby on the Infinite spaceship. With the open world concept kind of thing, but on the lobby you have the section with the standard campaign missions.
* Playable elites and dual weild.
* Return of co-op vehicles like the falcon and spectre. Return of brute vehicles and maybe even vehicles from Halo Wars.
* Let the H5 weapon pool stay + return of the missing weapons. HCE: AR, plasmarifle, plasmapistol, magnum, sniper & shotgun. H2: Bruteshot, beam rifle & sentinel beam. H3: Mauler, carbine, spiker & flamethrower. H4: Sticky detonator & DMR. HR: Concussion rifle, focus rifle, needlerifle, target locator & plasmalauncher.
* HCE/H2/H3 inspired main menu. Everything blue, rotating and with never forget music.
* H5 forge, custom browser, file share & roster.
* Voting system in MP.
* Reach ranking, customization & credit system.
* Terminals like in HCE & H2 anniversary. Skulls & easter eggs.
* To be able to pick up the hunter claw after killing a hunter. To pick up and be able to use the jackal shield.
* To face hunters in their natural form in campaign like in Halo Nightfall. + new alien species and maybe we can see more forerunners instead of just prometheans.
* H5 spartan ID with loadoats, weapon skins, assassinations, announcers and stances.
* Instead of all the armor and vehicle variants we would be able to just customize our own warthog and moongose with skins. The patterns and white stripes on the armor should just be a changeable option.
* Cloaks and gillysuits.
* Spartan Ops with campaign missions from the older games, like a mission from H3:ODST, Reach and even with fireteams from the books. It doesn't need to be connected story, just a oppurtunity to experience teams in a modern FPS.
* Reach & ODST firefight with option to customize your enemies. You can choose to fight flood for example.
* MP would consist of: Social, Ranked, Classic, Warzone, Firefight & Spartan Ops.
* Sidequest if it's a open world game.
* Underwater & space missions.
* Warzone should have a more variety of maps. Forest, cave, underwater, covenant spaceship, Infinity spaceship etc.
* No spartan abilities & armor abilities in campaign, only in MP. Equipment items is fine.
* Special armor, vehicles and weapons unlocked through finding all skulls or terminals for example.
