This is my opinion of what makes a Halo perfect:
Weapons:
Humans:
Assault rifle, battle rifle, DMR, sniper rifle, SMG, shotgun, magnum (Halo CEA & 2 version), spartan laser,
rocket launcher, grenade launcher, railgun, saw, the target locator, sticky detonator, hydra.
Covenant:
Storm rifle, plasma rifle, plasma repeater, plasma pistol, plasma launcher, fuel rod cannon, concussion rifle, needler, needle rifle, covenant carbine, fusion rifle, beam rifle, energy sword.
Brutes:
Spiker, mauler, gravity hammer, brute shot.
Forerunners:
Boltshot, light rifle, suppressor, binary rifle, scattershot, inceneration cannon, sentinel beam.
The perfect weapon adding:
Weapon skin for every weapon and every weapon could be used in your loadout (and you get more skins and weapons as your rank gets higher).
Dual weild, assasination with gravity hammer, pulse/plasma grenade, energy sword and the combat knife.
In ODST you have silencer on the SMG, so If you could change your scope and put silencer on human weapons that would be great!
Missions:
My favorite missions from the Master Chief Collection:
Halo CE:
A night sneak mission where you begin with a sniper rifle like The Truth and Reconciliation, and you need to get
on a covenant ship to free prisoners like Keyes and the other marines. The good old Halo CE music is very important to a mission like that. It makes a good atmosphere.
Two Betrayals are so enjoyable to play because of the snow, banshees, flood and the covenant chaos and it has a real fun start when you begin with a plasma pistol to shoot down all the sentinels. The bridges you have to walk between the icy mountains to come to other sections are real fun to play too.
Halo 2:
Delta Halo because you start off in a drop pod as Master Chief and invades a map of jungle and ruins, and fights along with ODST marines. It’s really fun to play through these ruins.
Uprising is so fun to play because you start as the Arbiter alone and fights against the brutes, and it’s so cool when the Arbiter and Sgt. Johnson meets for the first time. The Elites vs Brutes makes it’s so cool to play.
Halo 3:
Crow’s nest is one of my favorite campaign missions. I love when you hear the noises from the drones and I love to fight them. They’re one of the most annoying and coolest enemy.
Halo is so fun to play. I like when you crashes in the snow inside a mountain with a pelican and soon you meet so much different flood forms and sentinels and that is so enjoyable. The moment when you have to kill the monitor and when Sgt. Johnson dies is just legendary, and the driving before everything collapse is just the best part of it all!
Halo 4:
Shutdown because it’s cool to fly around in a pelican and fly to different locations to take out and discover forerunner technology.
Midnight because it’s so awesome when you fly and try to avoid every obstacle and when you jump from place to place and finally gets to the Didact, trying to finish him.
What the perfect campaign needs:
- Elites, grunts, jackals, brutes, sentinels, drones, engineers, hunters, knights, crawlers, watchers, all kinds of Flood (Humans, Covenant and Forerunners).
- Colony conflicts (like the covenant conflict in Halo 2).
- Boss battles like in the missions: The Oracle, Regret, The Great Journey and Midnight. In these missions you have to defeat The Heretic Leader, Prophet of Regret, The Brute Tartarus and The Didact and that is just awesome!
- All Halo weapons and enemies!
- The engineers should be used as extra shield makers for covenant and humans as the watchers are being used as extra shield makers.
- Night, snow, sneak, sniper, jungle, ruin, forest, cave, sea, ocean, flying missions.
- There should be a mission when you have to turn off the technology and sneak by hunter worms like in The Halo Nightfall and a mission where you are in a cave full of drones and crawlers.
- If the Chief is gonna die he needs the most heroic death ever! No question
