Halo Infinite is finally adding campaign co-op next month, developer 343 Industries announced today. This will begin with a early test, or “flight,” that will run starting the week of July 15.
Microsoft is only testing online campaign co-op, so fans hoping to play split-screen co-op locally still have to wait for an undetermined point in the future for that. 343 had always said it would hold a test for online campaign co-op in July, but this is the first time it’s being officially dated for the public.
Players need to sign up for the free and open Halo Insider program to get into the flight. The test is part of a separate version of Halo Infinite, so any progress you’ve already made in Halo Infinite’s campaign will not be applied in the network co-op test, nor will any progress you make in the test move with you to any existing campaign save you may have already.
