343 Industries has provided a Halo Infinite roadmap for its ongoing live service strategy, beginning with the game's biggest update so far this November and stretching through Season 3 in March 2023.
The free Winter Update is set for release on November 8, and this will be Halo Infinite's largest content update so far. It includes a beta for Forge, the online campaign co-op and mission replay features, a new 30-level battle pass for free, two new maps, and--finallyone each for Arena and Big Team Battle--are coming in Season 3 as well, along with new VIP and Escalation game modes.
Additionally, the rumored Bandit Rifle will be added to Halo Infinite in Season 3. It's similar to Halo: Reach's DMR, 343 said, though it is more effective at close range. There is a new Shroud Screen ability coming, too, that "focuses on area denial through a high-tech smokescreen that conceals players from radar, even when firing, but at the cost of completely obscuring vision both into and out of the screen."
Finally, 343 Season 3 in 2022 will mark the beginning of a "more predictable" schedule of live-service seasons for Halo Infinite. There will be "more content than ever launching throughout each calendar year," 343 said.
In addition to ongoing updates for Halo Infinite, Season 2 of the Halo TV series is in the works.
