343 Industries has announced that they need more time to work on the co-op modes for the Halo Infinite campaign. This is the first Halo game to ship without co-op for both local play and online co-op but it looks like fans will need to wait a bit longer for it.
The team posted an updated on the anticipated co-op experience to Halo Waypoint (https://www.halowaypoint.com/news/halo-infinite-update-march-2022). The lengthy post explains that “it’s going to take more time to land a high-quality, full-feaured 2-player network co-op experience” in Halo Infinite.
The team notes that they are also committed to 2-player split-screen co-op experience on all Xbox consoles which has also caused delays. They state that “the non-linear, wide-open sections of the Campaign present some big challenges for split-screen” which needs more time to solve.
This means they cannot ship Campaign online co-op on May 3rd at the start of Season 2. 343 Industries is aiming to add this feature later in Season 2 and will have a new release date for it soon.
