The Halo Infinite co-op beta has been delayed until the end of this week or next. In June, the developers assured that testing would begin on July 11, 2022.
The news was announced by community manager Brian Jarrard, who tweeted:
…the team is still working on the upcoming Halo Infinite Insider Build for online co-op play. Although we reported that "our target was the week starting July 11th," many sites indicated that the beta test would begin on July 11th. Still hoping for this week, but it won't start today.
Jarrard explained that 343 Industries was facing some unresolved issues.
We apologize to everyone who was expecting the start today. We really want to bring the game to you, but we also want it to be a positive, rewarding and ongoing experience. Thanks for your patience and understanding.
