Heh?
Plenty of games do this now. The technology has existed for many years.
Look at Ghost Recon: Wildlands, AC: Valhalla, RDR2, Far Cry, Ghosts of Tsushima etc. So many games with vast open worlds that encompass a day/night cycle and full weather system.
And from reports Halo: Infinite is not even full open world. It’s semi open world. Kind of like ODST.
“The technology” isn’t a real thing, you can’t just copy and paste one games solution to the problem and have it work in another game. They’re different games, running on different engines. I’m not saying it would be impossible, it definitely wouldn’t, but in game development you always have to prioritise and cut features that are outside the scope of your development deadline. I’m sure the relevant design teams at 343 were looking at weather effects, prototyped some, then considered the time and the cost needed to implement them well across all the different SKU’s the game is launching on and decided to focus their priorities elsewhere.
As for whether the game is truly open world or not doesn’t really matter. All games will only load in assets the player is looking at, so what matters is the scale of each playable space, the distance you can see and the speed you travel. Halo Infinite, whether its truly open world or not, easily has large enough environments that it could create issues for a game developer looking at weather effects.
Also very concerned about this. Feeling like the campaign will be pretty dull and monotonous without any major changes of biome. Sure there will be more biomes eventually, but they’ll certainly cost money.
A common theme with many games is that the developers are highly restrictive with revealing too many details about the game. If we take Halo 5 as an example, the individuals who got the press copy of the game where only allowed to show footage or share details from the missions Osiris, Blue Team, Glassed and the first half of Swords of Shanghelios before the release date of the game.
If we would also take into account other messages before the release of the game, the environment in the mission Reunion/Genesis, The Breaking, Guardians wasn’t announced before the release of the game itself. A similar thing can probably also be said about many other Halo games that a large portion of the gameplay environments got revealed at game release.
Are you sure about that? I made a list of all known environments before release and I think I covered ever unique environment that was in the campaign…
While there’ll be more campaigns, I highly doubt it’ll be on Zeta Halo. We’re not spending 10 years at 1 location 
There are alot of options where it can go after zeta halo, I can see it heading eventually to the greater arc.
Thanks to the Marketing team we might not see many biomes. I think originally 343 was going to have us play on an entire halo ring they wanted us to be able to jump in a banshee and fly the whole ring. Then Marketing stepped in and said wait, wait, hold on, Why not chop that up so we can charge more for that! So Maybe over the next decade of paid DLC we’ll finally get to explore an entire ring world like I’ve wanted too for 20 years.
Isn’t zeta halo supposed to be like 30,000 km wide? I guess with the chunks blown off, at a guess I’d say it’s still around 7,000,000 km squared.
It would be awesome to explore a whole ring, guess could fill out half of it with ocean, even then it’s alot of biomes
That’s an ambitious theory. I think you would be waiting another 20 years for that game.
Are you sure?
Zeta Halo was surely picked because it has such strong ties to the lore and potential story threads on it. They’ve picked a place with ten years of stories to tell.

Yeah, we’re def not spending 10 years at only 1 location. Would get limiting pretty quick. We’re def gonna be going to other places in later campaigns.
This is probably my only critique with Infinite’s campaign so far. I want to see snowy Forerunner structures or being able to fight the banished on a beach. Even if these type of environments don’t come launch, I’m sure they’ll eventually add something down the line.
its a big ring, i would like to see the beach and some sort of jungle
OK so 1 biome but with weather conditions and sub biome.
To those saying we won’t spend ten years on zeta I expect it will be in play for the decade just not the sole location. Its a big place with many many secrets not particularly limiting in any way story wise.
At first the PNW focus was a disappointment for me but in hindsight if this means each major expansion introduced a new biome with unique sandbox traits then this could be kne of the best choices the series has ever made in my opinion.
PNW is pretty varied, not just brown trees.
There is plenty of time for Infinite to expand into other biomes. We aren’t going to be stuck on Zeta Halo for the next decade. Until then we only need the biomes that 343 need to tell (this part of) their story.
I know they said it will remain mostly similar throughout the campaign for terrain but I’m hoping there’ll be more differences like snow or something in some areas.
Damn, watched the final launch trailer and it all but confirms to me that the entire game is green and gray. Sucks, there were so many unique and beautiful locations in Halo 3 or Reach. Starting to feel like all of my concerns about Infinite are coming true…
There was mention of dynamic weather apart from the wind and fog, it’s likely rain and snow showers will come at some point, and no doubt expansions or new campaigns will bring in other more varied terrain.
