Selvom verdenen i Halo Infinite ikke er GTA-åben, så er det dog seriens mest åbne spil til dato, og her er der en række parametre der påvirker dine chancer i kamp, deriblandt vejrforhold og hvilket tidspunkt på dagen du vælger at eksempelvis angribe en fjendtlig base.
Dette forklarer 343's Justin Dinges og John Mulkey lidt om i en ny video, hvor han slår fast at fjender opfører sig anderledes, og er grupperet anderledes alt efter situationen.
I forhold til vejr siger Dinges:
"Part of our job on the art team and the graphics team was to make the ring feel alive, and being a part of a big ecosystem, and a big part of that is weather, at least on our planet, and we want to emulate that on the ring. So we've definetly added things like a really cool wind system, which is not just visual but also audio. There's also a fog system. We didn't go down the road of having rain storms, thunderstorms and snow storms, and things like that."
Og betyder det noget om det er nat eller dag? Det svarer Mulkey på:
"So when you're moving through the world in the darker periods, yoiu're gonna end up seeing more patrols of Phantoms with searchlights, which is pretty cool. You'll probably run into more opportunities where grunts are sleeping on the job. We've also worked on just having things that would look cool in dark spaces, so we're going with things that have more emisives on them. So you're going to run into more Shield Jackals for instance, that eminate light."
