When all hope is lost and humanity's fate hangs in the balance, the Master Chief is ready to confront the most ruthless foe he's ever faced. The Halo series returns with the most expansive Master Chief story yet and a ground-breaking free-to-play multiplayer experience.

This next chapter in 343 Industries' legendary Halo franchise invites players to join the venerable Master Chief on an all-new adventure as he uncovers the mysteries surrounding the appearance of "The Pilot" and the desolate remains of a Halo ring.

Begin anew and step inside the armor of humanity's greatest hero to experience an epic adventure and finally explore the scale of the Halo ring itself.

Explore the epic expanse of a Halo ring for the first time in the most ambitious Halo game ever made.

Campaign Network Co-Op for Halo Infinite is on its way and you’ll soon be able to take the fight to the Banished with your friends and family in the upcoming flight, which is targeted to run from the week of July 15.

You’ll use the same system players are already familiar with from Halo Infinite’s Multiplayer to form a Fireteam. Once your Fireteam is formed, you can just pick “Start Co-Op” from the main menu. It’s that easy!

Halo campaigns aren’t something players tend to go through once, but replay many times over—whether you’re in it for the story, the gameplay, speedrunning, finding tricks and glitches, Skull hunting, and all the other accoutrements that give Halo campaigns a special place in the hearts of many.

It has been a long-time tradition in the Halo franchise that once you complete a mission, you can go back and replay it for fun, to unlock achievements, to find collectibles, and so on. In previous titles, this was a straightforward proposition since those games were assembled from a series of self-contained "levels."

With Halo Infinite, we introduced a more open and explorative element to the campaign paradigm. This necessitated some changes to the way Mission Replay works to ensure we can enable the option to the player while ensuring we maintain the integrity of the experience and the game state.

What are the requirements and necessary steps for someone to participate in this upcoming flight?

It’s simple! Here's a quick blurb, but keep an eye out for full instructions once the flight is officially underway.

Step 1: Make sure you’re signed up to the Halo Insider program.

Step 2: Ensure you have the entitlement to Halo Infinite (Campaign). (i.e. you have purchased it or have an active Xbox Game Pass subscription)

Step 3: If you’re participating on Xbox, have the Xbox Insider app downloaded, and opt into the Network Co-Op flight program once the flight is live. If you’re playing on Steam, you’ll be sent a unique key via Halo Insider communications to download the flighting build.

Step 4: Launch the build, party up with friends, and jump into Zeta Halo!

The full Halo Infinite Campaign will be available to play via online co-op while the beta is available, and due to the nature of this new build all players will need to download the campaign build and start a fresh campaign playthrough as no previous progress will carry over. As missions are completed in the beta, they will also become available to revisit as part of Mission Replay.

The Network Co-Op flight is conducted on a separate build intended to test the features without affecting your existing retail copy of Halo Infinite, as such progress made in the beta will not transfer back into the retail version of the game.
