Halo: Campaign Evolved’s co-op isn’t just a return to its roots, but a complete reimagining of the iconic campaign. For the first time in the series’ history, you can play through the story with up to four players, and across multiple platforms: PS5, Xbox Series X|S, and PC—all in a single squad. The developers at Halo Studios have injected new life into the game: cross-progression, the ability to customize Spartan appearances (online), and three additional prologue missions, “Operation: METEORITE.” The game will be released on July 28, 2026, with Premium Edition owners getting early access starting July 23. Here’s a detailed guide to all the modes, nuances, and hidden features.

Setting up split-screen and single-screen co-op mode
Split-screen mode is a classic feature of the genre, but the new version has some important limitations. This mode is only available on consoles (PS5, Xbox Series X|S)—it’s not available on PC. Co-op play is possible, but be prepared for some compromises.
Step-by-step instructions:
-
Launch Halo: Campaign Evolved on your console. Make sure at least one player is logged in to their account (PSN or Xbox Live).
-
Connect a second controller—the system will automatically prompt you to join. A “Join Player 2” button will appear on the screen.
-
The second player presses A (on Xbox) or X (on PlayStation) to join the squad.
-
On PlayStation, there’s an additional step: Player 2 will need to sign in to their PSN account, which is linked to their Microsoft account. Co-op will not work without this.
An important detail: split-screen play on PS5 does not require a PlayStation Plus subscription—this is an official clarification from Halo Studios, which many reviewers missed.
Player 2 can’t change armor or weapons—their Spartan uses the leader’s settings. This is the only area where customization is limited.
The pace of split-screen play remains fast, but the field of view is narrower—learn to work together and stay in touch.
Four-player online co-op and cross-play features
The main new feature is the ability to assemble a squad of up to four players, from different ecosystems. Crossplay works between PS5, Xbox, and PC, and cross-progression syncs saves via the Microsoft cloud.
Connection process:
-
In the main menu, select “Play Co-op.”
-
You will see two friend lists: “Friends on the same platform” (those playing on the same console or Steam) and “Cross-platform Friends”—these require a Gamertag or an email address linked to a Microsoft account.
-
Send invites until all four players are in the squad. Then click “Start Campaign.”
-
In your account settings (also in the main menu), make sure the crossplay slider is enabled—otherwise, you won’t see players from other platforms.
Important: If the squad leader leaves the session, the game will end for everyone and you’ll be returned to the main menu. Progress is saved only for the leader, but all unlocked skulls, terminals, and completed missions are also reflected in your personal campaign. So, if the leader has already collected all the collectibles, you’ll receive them in your profile—but only for the current playthrough. To replay the campaign with your progress, you’ll need to become the leader yourself.
Co-op innovations and comparisons to the 2001 original
The 2001 Halo: Combat Evolved was remembered only for its local two-player split-screen mode—there was no online mode whatsoever. The new version surpasses the classic on all fronts, offering much more than just cosmetic updates.
Key Features:
-
2 players instead of 4 online (plus classic two-player split-screen mode).
-
Crossplay and cross-progression—your saves carry over between platforms, simplifying the transition from PS5 to PC.
-
Sprinting is now available—you can disable it in the settings if you prefer a pure retro experience.
-
Three new “Operation: METEORITE” prologue missions featuring Master Chief and Sergeant Johnson—they take place before the fall of the Pillar of Oath.
-
Levels have been redesigned with four players in mind: enemy numbers have been scaled, and passages and cover have been adjusted. For example, in the mission “Truth and Reconciliation,” additional flank routes have been added to prevent the squad from getting crowded in narrow corridors.
-
Skulls have been relocated—finding them now requires meticulous exploration of every corner; they don’t match the original locations. This is a tribute to veterans who knew the map by heart.
-
Remix and LASO modes—the former shuffles enemies and weapons in each mission, the latter includes all skulls at the highest difficulty. Both are available in co-op.
For clarity, here’s a comparison table:
As you can see, the gameplay changes aren’t limited to the number of players—it’s a complete redesign that makes co-op feel fresh even for those who’ve played through the original dozens of times.
Spartan Customization and Armor Skins in Co-op
In online co-op, each player can customize their appearance—and that offers a vast array of content. As a reminder, the second player is deprived of this option in split-screen mode, but online you are completely free.
Available skin sets and methods of obtaining
-
Foundry Armory Pack – a bonus for pre-ordering any edition. Includes two armor skins (“Steel Legion” and “Shadow Patrol”) and two weapon skins for the MA5B and M6D pistol.
-
Classic 2001 Mark V – the famous green armor from the very first game. Available to all players from the start.
-
Gilded Onyx – a black and gold style inspired by Forerunner architecture. Unlocked by completing special missions in Remix mode.
-
Premium / Collector’s Edition unlocks the Alpha Halo Armory Pack – a whopping 5 armor skins and 6 weapon skins, including “Olwen’s Ghost” and “Blood Dawn.”
All skins affect the overall aesthetic of your squad—you can assemble a team of completely different Spartans, from classic to futuristic. Unlike split-screen, online, everyone can equip their own loadout.
Tip: If you’re playing with friends on different platforms, remember that skins are linked to your Microsoft account and transfer between platforms—so your collection always comes with you.
Answers to frequently asked questions about co-op play
Saving progress with the group leader
Do co-op campaign sessions continue where the squad leader left off?
Yes, including available missions and skulls. The leader’s progress is the foundation for the entire session.
Consequences of the leader leaving the game session
Does the leader exit the session?
Yes, all players are returned to the main menu. The game saves automatically upon exiting.
Paid subscription required for online play
Do I need a subscription to play co-op?
For online play, yes, Xbox Game Pass Core/Ultimate or PlayStation Plus (Essential or higher) is required. Split-screen play on consoles doesn’t require a subscription—this is an important clarification for PS5.
Transferring items and skulls to a personal campaign
Does co-op progress carry over to your personal campaign?
Yes. All unlocked missions, skulls, and terminals remain in your profile, even if you weren’t the leader. The only exception is if you join a leader who has already completed the game and collected all the skulls, you’ll have access to them in their session, but they won’t appear in your campaign—you’ll have to find them yourself.
Linking a Microsoft account and its consequences
Can I unlink my Microsoft account after linking it?
No. This is a permanent link—the developers suggest it’s needed for cross-progression and a unified friend system. So choose your account wisely.
Support for custom modifications on PC
Will co-op support mods on PC?
There’s no official confirmation at this time. Halo Studios stated that they are focused on the stability of the base game, but haven’t ruled out community support in future updates. In Halo: Campaign Evolved, co-op goes far beyond just another mode, becoming the core mechanic of the entire gameplay experience. The game launches on July 28th, and if you’ve been yearning for a true team-based experience with friends, this version will give you exactly what you’ve been waiting for. Happy fighting, Spartans!
