Halo developer 343 Industries have hosted a live stream, showing off the co-op mode for Halo Infinite, something that they promised was coming and those who want to play now, can do so through the early access, check it out below.

There are some details to be aware of, for example story progress:

When the Fireteam Leader starts a co-op campaign session, all players in the Fireteam will be prompted to select their save file. Using the selected save files, the Fireteam’s campaign progress is aggregated so that the session’s progress reflects content that all members have completed. This allows all progress made in co-op sessions to be applied to each player’s individual save file.

Head over the the Halo Support site for the full details. The early access is only around until the 1st of August, so a few weeks, but beyond that there is no date on when it will roll out in full.
