Last month 343 Industries confirmed that a playtest would take place for Halo Infinite’s campaign co-op, and now a date is set in stone.
In classic Halo fashion, every character simply plays as the Chief in campaign co-op, rather than explaining it with some kind of lore reason.
One of the big things is that every player will retain their progress whether in solo or co-op play.
Those that are lucky enough to take part in the playtest will be able to drop in with their friends starting the week of July 11, as announced in a Halo Waypoint blog post.
