With such a comprehensive, detailed, and large article it's hard to know where to start commenting.

As a general principle: I would let campaign and mp play diverge. For example: if mp players hate grenade spamming and want them nerfed in some way then nerf them in mp. Don't make campaign players suffer to make mp players happy.

I agree that that features can be dropped, that you don't need to preserve a feature just because it was added at some point. The classic example being duel wielding. There are many features that I just wouldn't miss if removed from the game.

I don't miss the Halo 3 pickups: grav lift, bubble shield, invulnerability, etc. And the only armour ability I would miss would be sprint. I don't think its a must have but I have got used to it being around. If it was in the game then I'd have it innate. It wouldn't be traded for something else, it wouldn't have a battery. Sprinting is just something that people can do.

Talking of things not missed... I would not miss the slow to execute air attack thingy. I would rather that it was gone. The boost? meh.

The Spartan charge was useful but maybe I'd just make it a melee attack that is enabled when sprinting. I wouldn't have a dedicated button for it, run at someone, press the melee button.

I like original game health, it is my preference, but could live with regenerating health.

Just say NO! to any revive mechanisms. I never want to see the Chief grovel on the ground. I couldn't see the 'science' behind it, and if I saw an enemy weakened but waiting for help then I would put a few extra bullets to finish him and forestall help. There is no way any enemy would give you the opportunity to be revived.

Agree for removing emp in campaign for vehicles. I'd certainly stop it affecting UNSC vehicles. Plasma is good against shields, maybe it's good against anti-grav. But EMP certainly makes vehicles less fun to use.

Agree that vehicle damage model needs changing. At times you feel more vulnerable in a vehicle as you have gained a larger hitbox - why should shots against a fender weaken my shields?

Vehicles shouldn't be damaged because the player is damaged. You'b be able to board a Wraith, kill the driver and only damage the hatch - the vehicle wouldn't explode if you meleed the driver to death.

I'd like to be able to board a Wraith from behind and then be able to clamber to the front to kill the diver.

In campaign a vehicle should take little damage from small arms but be damaged by heavier weapons: turrets, FRGs, etc.

Definitely agree that small arms shouldn't be able to move vehicles (except empty ones for the benefit of trickers, or maybe have it toggled by cowbell? skull)

I'd like enemy invis to use the same mechanism as their shields. They lose their shields when invisible. So they are sneaky but vulnerable just as they were in the original game.

Ally AI is shockingly poor and hasn't improved, enough, since Halo 3. I doubt that things will ever improve so just don't saddle us with distinguished allies (allies that are not supposed to be ineffectual idiots). Give us ordinary marines who can die and aren't super soldiers so their suckage is less jarring.

things I'd like to see

A falcon variant without the tail structure

Put tail fins on top and use vectored thrust for steering. Have a LAAG style gun suspended from the ceiling that can be walked around the periphery of the passenger section and can shoot up, down, and behind.

Non euclidean geometries

• levels with curvature so we have horizons and stuff over the horizon until be get close
• hollow cylindrical habitats
• hollow spherical worlds
