Halo Infinite's online campaign co-op is coming in August, but developer 343 Industries will begin to test the feature publicly starting in July. In a tweet, the company said the plan right now is to test the feature, or "flight" it, in the Halo parlance, beginning next month for Halo Insiders.

The Halo Insider program is free and open to everyone. Players can register for Halo Insider here and opt in for beta tests for a chance to get in.

Community manager John Junyszek said in another tweet that the team at 343 is currently "heads down focusing on quality-of-life updates" for Halo Infinite. More information about the campaign network co-op test will be shared later this month.
