Hunter assassinations. It was said somewhere that a prototype assassination of a Hunter was made using Halo 3… God I’m just dying to shove a grenade into a hunter’s back or punching the hell out of it and then have it shake me off.
More armor customization options please!! Ever since Halo 3 and Halo Reach further advanced it, it was the best thing ever. And I was glad Halo 4 had carried it on in a simpler fashion, but after not having it in Halo 5, I was very disappointed as there just so much more variability we can have than skins. I have been advocating this since launch and I would want to see this come back. It can even dilute the req pool for the next game too by a lot since there are so many variations of armor.
More Classic weapons/vehicles. I think the iconic scorpion tank and wraith should definitely come back. If we got the classic Beam Rifle, why not the Halo reach/CEA/H2A Sniper rifle (The halo reach model should be used since it was also used in Halo CEA and Halo 2A)
B.O.B for firefight?
Brute Chieftains as a boss and having brutes as part of a wave. Since they are a problem in Halo Wars 2 and the events of it take place during Halo 5, it would make sense for spartans to be trained to fight against them. Especially against the Banished, if they are still a problem after Halo wars 2. Maybe even have brute weapons too like the spiker and spike grenade
Classic Firefight or Warzone Firefight Assault. Endless, endless waves of enemies that you must survive through. And every wave gets harder and harder. I would be glad if this were to come back, but in Halo Reach and ODST, they had maps dedicated for this, so I thought warzone assault maps could just have this and you must defend the objectives from them. They are not too small but big enough for this.
Changeable in-game user HUD color.
Turret armor mod, overheat less and increased movement speed.
Small ordinance drops for rounds for Warzone Firefight.
