Is the campaign in Halo Infinite playable in co-op mode?

As of the last update before my knowledge cutoff in early 2023, the campaign in Halo Infinite was not playable in co-op mode. The developers at 343 Industries had stated their intention to add this feature post-launch, with plans for both online and split-screen cooperative play to be included in a future update. Players worldwide have been eagerly anticipating this addition, as cooperative gameplay has been a staple and much-loved aspect of previous games in the Halo series. However, it is recommended to check the latest updates from the developers or on official Halo channels for any new announcements or changes regarding co-op functionality in Halo Infinite's campaign.
