Players will each control their version of Master Chief as they play co-op.

While Halo 5: Guardians introduced four-player co-op campaign for the first time ever, Infinite does one better by allowing four players to play together in a big open-world Master Chief campaign. As per a recent Halo Infinite blog post, here’s the step-by-step process for gamers wanting to hop on with friends and play through the Halo Infinite campaign together.

To start a Network Co-Op Campaign session, follow the steps below:

1. Launch Halo Infinite.
2. Select the “+” symbol underneath your Nameplate to add players to your Fireteam.
3. From the Social menu, select the Friends tab.
4. From here you can join a friend’s Fireteam or invite them to join yours by selecting their Gamertag and choosing from the options on their Profile menu.
5. Once the Fireteam has been formed, the Fireteam Leader (FTL) should navigate to the Campaign menu in the Play tab. The FTL is identified by a crown icon in the Fireteam widget located in the bottom left of the screen and in the Social
6. In the Campaign menu, the FTL can select to Continue their latest save file, start a new save file, or load a specific save file.
7. Once the FTL selects their save file, they will enter the Campaign Co-Op menu where they can select the preferred Difficulty level and which Skulls to enable.
8. After pressing the Start Co-Op button, the rest of the Fireteam will be prompted to select their save file.
9. The FTL can select Start Game to initiate the session once all players select their save file.

No Spartan Left Behind System

One element that the dev team spoke about in detail was the way player progress will transfer over from solo and co-op campaign run-throughs.

While previously, every Halo game would separate your solo and co-op progression. Halo Infinite will merge the two. This allows for constant retention of progress, regardless of how many other others, if any, players choose to engage in the campaign. 

Lead World Designer John Mukley had this to say when breaking down this new development for Halo’s proposed co-op experience: “I could be playing Solo campaign, jump into a Co-Op session for a few hours, then launch back into Solo play and all the mission progress, acquired collectibles, equipment found, achievements earned, and upgrades made in either session would be intact. Gone are the days of playing someone else’s game while earning no progress.”

Up to four players will be able to replay Halo Infinite’s campaign together

Playing through Halo Infinite’s campaign in co-op will still allow players to upgrade Chief’s abilities. Spartan Cores, the item that serves as the leveling-up tool for the different power-ups Chief unlocks throughout the campaign, will still be available to find.

When playing co-op, if a player stumbles across a Spartan Core and picks it up, all other players who have not already acquired the specific core will get credit for it also. Players are then left to their own devices in regards to how and what they choose to level up.

“This means that you get the benefits of working together, but you also have the room for self-expression with your personal playstyle,” said Isaac Bender. 

“If one of you wants to focus on upgrading your Drop Wall to protect yourself while your partner gets the Grappleshot melee upgrade to charge into the enemies’ ranks, you can do that.”

Halo Infinite co-op: Platforms and cross-play compatibility

Co-op for Halo Infinite is available on the Xbox One, Xbox Series S/X, and PC. As well as this, cross-platform support will be featured so that PC players can still play co-op with their console friends.

When asked about cross-play compatibility, Principal Software Engineer Lead Isaac Bender detailed that “there are differences in graphics quality and frame-rate, but this applies equally to single-player.

He then went on to explain that “any combination of PCs and Xboxes up to four players are supported, as is playing over Xbox Cloud Gaming. All Co-Op games are hosted on dedicated servers.”

To hop into a co-op campaign. Players will simply utilize the Fireteam system that is featured when linking up to play multiplayer with friends at the moment.

“Everyone’s progress counts,” began Bender when discussing how the co-op campaign system will work.

“So you’ll pick which save slot you want your Co-Op progress to count towards. After everyone has picked their save slot, you’ll get a summary of where your team will be starting, based on the “No Spartan Left Behind” system that I described above.”

Mission replay getting brought in, finally

Halo players will now be able to tackle missions in a new way with co-op.

One of the most controversial omissions for the launch of Halo Infinite was the lack of replayability when it came to the game’s campaign. While players are usually able to replay campaign missions to their heart’s delight, Infinite disallowed this up until now.

To replay missions, players simply highlight the mission they wish to play through and select replay. The game will then give you the option to select difficulty and activate skulls before the Fireteam is then transported over to begin the mission.

Players will also retain all progress and upgraded gear even if certain abilities were not accessible when the mission was originally played through. In essence, it means you’ll be able to go back to the first mission and smash through it with a fully upgraded Master Chief.
