Im taking a survey and seeing what people want halo 5 to have its just to ask the question.
On the top of my head, split-screen, elites.
UNSC air vehicles.
H3 ranking/social setup
The first thing that comes to mind is Invasion. It was one of my favorite game mods from Reach. I also think that there should definitily be some sort of UNSC air vehicle and the Halo: Reach armor look. I feel that Halo 4 and 5’s armor looks too… Polished. I don’t know, I guess it’s a matter of opinion.
Sprint!
yes definitely a real sprint not a speed walk
Extensive armor customization…
Here’s my Personal Top 5
- FULL Armor Customization
- SPNKR Rocket Launcher as the base Rocket Launcher.
- Playable Elites.
- Split-Screen.
- No Halo 2 Anniversary Warthog Horn. (I found out this one was fulfilled after watching the third Halo 5 mission.)

I second this. Full Armor Customization was my favorite thing about both Halo: Reach and Halo 4.
Brutes, Flood (put them in warzone)
Vehicles in 4v4 maps
Race
Falcon
Forklifts
Needle rifle.
Flaming Recon! Or something else to replace that.
In addition to all the other things above, I’d love to see;
-
A refined firefight or Spartan ops mode, or even BOTH!
-
Refining and balancing dual wielding so it can work in the sandbox. Even having it nerfed compared to singular weapons would be cool. I just enjoyed it for its sheer awesomeness and “fun/badass” factor.
Dual wielding
Firefight. 
And, possibly a social hub to walk around, to get immersed more into the universe.
Campaign Theater
Falcon
Split-Screen
Full Armor customization
Race mode
Invasion
Or some other form of asymmetrical multiplayer, where one team is Spartans and the other team looks/plays differently
That could mean they’re Elites or something else
All of the gametypes they took out of the game. Which is a LOT.
