Play Halo 4’s campaign first, then play Spartan Ops if you want the complete Halo 4 story. After that, you can start Halo: New Covenant, but Halo 4 is not a required prerequisite: New Covenant is a community campaign mod for Halo 3: ODST, not an official sequel to Halo 4. Its Workshop description places it after Halo 3.

The answer in one minute

There are two different questions hidden in the title. For the official Halo storyline, Halo 4 follows Halo 3. Within Halo 4, the recommended order is the main campaign followed by Spartan Ops. Xbox Wire describes Spartan Ops as episodic story content that continues directly from the end of the campaign.

Halo: New Covenant is a separate, fan-made project. Its Steam Workshop listing describes it as a campaign mod for Halo 3: ODST and sets it after Halo 3. It is not the official game that follows Halo 4, and its listing does not make Halo 4 a requirement. You may play Halo 4 first for additional Halo context, but you do not need to finish it to understand the mod’s stated setup.

What Halo 4 adds to the series

Microsoft’s November 5, 2012 launch announcement places Halo 4 nearly five years after the events of Halo 3. Master Chief and Cortana enter a mysterious new world and encounter an ancient threat. The game begins the Reclaimer Saga, so it introduces characters, conflicts and terminology that become important to later official Halo stories.

  • 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.

That position makes Halo 4 useful background even when you are primarily interested in a fan project. It shows the status of Chief and Cortana after the original trilogy and establishes the direction of the post-Halo 3 setting. It does not, however, turn every later community project into a direct Halo 4 sequel.

Where New Covenant fits

The Steam Workshop project titled Halo New Covenant is described as a community campaign mod built for Halo 3: ODST. The project’s own stated setting is after Halo 3. That makes it different from an official numbered installment and different from Halo 4’s Reclaimer Saga continuation.

Official game or fan project?

Do not use the title alone to infer release order. Microsoft’s official Halo announcements and Xbox Wire coverage identify the numbered games and their expansions; the Workshop page identifies New Covenant as a community modification. In October 2025, Xbox Wire also discussed Halo: Campaign Evolved, an officially announced remake project. That project is separate from the Workshop mod and should not be treated as the same game.

Do you need Halo 4 first?

No. If your goal is simply to start New Covenant, the mod’s stated starting point is after Halo 3, and the available project description does not specify Halo 4 as a prerequisite. Play Halo 4 first only if you want to follow the broader post-trilogy era or experience Halo 4’s own story before trying an unrelated community campaign.

Recommended orders for different goals

Goal Recommended order Why
Follow the official mainline story through Halo 4 Halo 3 → Halo 4 campaign Halo 4 is set nearly five years after Halo 3 and starts the Reclaimer Saga.
Experience all of Halo 4’s narrative content Halo 3 → Halo 4 campaign → Spartan Ops Spartan Ops picks up where the campaign concludes.
Start the New Covenant mod as soon as its premise allows Halo 3 (then install and play the mod) The Workshop description calls it an ODST campaign mod set after Halo 3.
Get extra post-trilogy context before the mod Halo 3 → Halo 4 campaign → optional Spartan Ops → New Covenant This gives you Halo 4’s setting and continuation without claiming the mod is an official sequel.

Multiplayer, Forge and other sandbox modes are not needed to understand either the Halo 4 campaign or the mod’s premise. Treat them as optional activities rather than story chapters.

Timeline in plain language

The simplest chronology is Halo 3, then a gap of almost five years, then Halo 4. Microsoft’s launch description specifically follows Master Chief and Cortana into a new world during that later period. The numbered sequel therefore belongs to the official post-trilogy continuity, while New Covenant uses an earlier point in the timeline: after Halo 3 and within the setting of Halo 3: ODST.

That distinction explains why two apparently conflicting play orders can both be sensible. A player following Microsoft’s mainline chronology should go from Halo 3 to Halo 4. A player following the Workshop project’s own premise can go from Halo 3 directly to New Covenant. The mod’s placement does not move simply because you decide to play Halo 4 first.

How to play Halo 4 in the right order

1. Choose an access route

The most straightforward current route is Halo: The Master Chief Collection (MCC), which includes Halo 4. Xbox Wire’s November 17, 2020 announcement documented PC availability through Xbox Game Pass for PC, the Microsoft Store and Steam, and described MCC optimization for Xbox Series X|S. Those were the options and terms reported at that time; storefront availability, pricing and subscription requirements can change, so confirm the listing you intend to use before buying or subscribing.

A second route is the original Xbox 360 release. A physical disc can still be relevant if you specifically want the 360 version, but used-copy condition and availability vary. The 360 version’s online-service limitations are materially different from MCC’s.

2. Start the main campaign

  1. Launch MCC or the Xbox 360 version of Halo 4.
  2. Open the campaign menu and select the main Halo 4 campaign, not Spartan Ops.
  3. Choose a difficulty appropriate for your group. Difficulty changes combat challenge, not the story order.
  4. Play the missions in the game’s listed sequence. Avoid jumping into Spartan Ops between campaign missions if you want the intended narrative progression.
  5. Finish the campaign before moving to Spartan Ops. The campaign’s ending is the handoff point for the episodic content.

3. Decide whether to play cooperatively

Halo 4’s campaign can be enjoyed alone or with other players, depending on the edition and platform features available to you. Cooperative play does not change the mission order. On legacy 360 hardware, local split-screen and LAN options remain among the features identified by Halo Support after the 2022 service reduction; service-dependent online functions may behave differently.

4. Move to Spartan Ops

After the campaign, open the Spartan Ops section from the Halo 4 menu. Xbox Wire characterizes these missions as weekly, episodic, cooperative story content that picks up where the main campaign concludes. Playing them after the campaign preserves that direct continuation.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Spartan Ops is optional if you only want the central campaign arc. It is the correct next step if you want the additional Halo 4 narrative rather than stopping at the campaign credits.

What Spartan Ops is—and what it is not

An episodic continuation

Spartan Ops uses separate mission episodes rather than adding those missions into the main campaign list. The episodes expand the post-campaign setting and are designed for cooperative play, although the precise way you play depends on your platform and available services.

Not a prerequisite for New Covenant

Because New Covenant is described as an ODST mod set after Halo 3, there is no established requirement to complete Spartan Ops before launching it. Completing Spartan Ops is a completeness choice for Halo 4, not a documented installation or story dependency for the Workshop project.

Cost and purchase considerations

There is no stable price that applies to every reader. MCC pricing, Game Pass terms, store editions and regional discounts change, so check the live Steam, Microsoft Store or Xbox listing when you are ready to buy. A subscription may provide access while active, whereas a purchase gives you the listed edition under that storefront’s terms.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The original Xbox 360 game is most often encountered as a used physical copy. Compare disc condition, case contents and seller return policy rather than assuming every inexpensive listing is interchangeable. A disc can provide the campaign even when legacy online features have been reduced, but it does not convert the 360 service environment into MCC’s modern service stack. If your priority is campaign-only play on existing 360 hardware, the disc may be sufficient; if you want current collection support or PC mod access, evaluate MCC instead.

Starting the New Covenant mod safely

Use the project’s current Steam Workshop page as the authority for installation instructions, supported game build and required files. The available project description establishes its format and setting, but it does not establish a universal, permanent set of compatibility steps. Workshop projects can change as creators update files or as the host game changes.

  1. Open the current Workshop listing for Halo New Covenant.
  2. Read the author’s stated prerequisites, supported version and installation notes before subscribing or downloading anything.
  3. Confirm that your copy of the required Halo 3: ODST host game is installed and updated as the project specifies.
  4. Install or subscribe using the method documented on that page; do not rely on an old video or an archived file path.
  5. Launch the host game and verify that the mod appears in the location the author documents.
  6. If it does not appear, stop and compare your game version, enabled content and file location with the current project instructions before deleting or replacing files.

Do not assume that Halo 4 files, Halo 4 campaign completion or Spartan Ops unlocks are needed for the mod. If the Workshop author later adds a dependency, follow that current project-specific instruction rather than an assumed series order.

Compatibility checklist

  • Identify the exact host game named by the creator: the project is described as an Halo 3: ODST campaign mod.
  • Check whether the page names a particular edition, build or platform.
  • Read update notes for changed prerequisites before launching an older save.
  • Keep original files safe until the mod is confirmed to work.
  • Use the author’s documented location for the mod in the game menu; do not infer it from another Halo title.

Platform and service differences

Route What you get Important caveat
MCC on PC Halo 4 in the modern collection, with the PC access routes documented by Xbox Wire in 2020. Verify the current Steam, Microsoft Store or subscription listing and the requirements for the Workshop project separately.
MCC on newer Xbox hardware Halo 4 through the collection, with MCC services rather than the original 360 service stack. Current edition, account and subscription terms depend on the live store listing.
Original Xbox 360 disc or digital release The original Halo 4 campaign and Spartan Ops experience on 360 hardware. Xbox 360 Halo online services were reduced or disabled on January 13, 2022; backward-compatible play of the original 360 game is also affected.

What the 2022 Xbox 360 change means

Halo Support states that Xbox 360 Halo servers were turned off or reduced on January 13, 2022. The campaign and Spartan Ops remain available, along with features such as custom games, Forge, split-screen and LAN identified in the support notice. Features that depend on the retired services are affected, so an original 360 copy should not be treated as having the same online behavior as MCC.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The change also affects backward-compatible play of the original 360 release on Xbox One and Xbox Series X|S. MCC is not impacted by that particular 360 sunset because it uses modernized services. This distinction matters when choosing between an inexpensive used disc and the collection: both can provide campaign access, but they do not provide identical service support.

Common mistakes and how to avoid them

Mistaking New Covenant for an official sequel

The name sounds like a numbered Halo follow-up, but the Workshop listing identifies a community mod for ODST. Keep official series chronology and fan-project chronology in separate notes when planning your playthrough.

Starting Spartan Ops before the campaign

Spartan Ops is the episodic continuation. Starting it first can expose you to post-campaign context prematurely. Finish the main campaign, then open Spartan Ops.

Assuming Halo 4 is required for the mod

The mod’s stated setup is after Halo 3, not after Halo 4. Halo 4 is useful optional background, not an established technical or narrative prerequisite.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Expecting the 360 version to behave like MCC

The 2022 service change applies to the original 360 service environment and to backward-compatible play of that original version. If you need current collection services, use MCC rather than assuming a 360 disc supplies the same functions.

Following outdated installation advice

Mod instructions can change. Use the current Workshop page’s requirements and supported-version notes, and avoid copying file replacements from an old guide that does not match your installation.

Three practical playthrough plans

Shortest route to the mod

  1. Play Halo 3 if you want the immediate official context named by the mod’s premise.
  2. Install New Covenant from its current Workshop instructions.
  3. Start the mod without waiting for Halo 4 or Spartan Ops.

This plan prioritizes the project’s stated setting and avoids adding optional games.

Halo 4 story-complete route

  1. Finish Halo 3.
  2. Play the complete Halo 4 campaign.
  3. Play Spartan Ops in its episodic order.
  4. Install and start New Covenant only after confirming its current host-game requirements.

This is the best choice if your priority is seeing all documented Halo 4 narrative content before exploring the community project.

Frequently asked questions

Is Halo: New Covenant an official Halo 4 follow-up?

No. Its Steam Workshop listing describes a community campaign mod for Halo 3: ODST. The project is separate from Microsoft’s numbered games and from the officially announced Halo: Campaign Evolved.

Do I need to own Halo 4 to install New Covenant?

Nothing in the project description identifies Halo 4 as a requirement. The relevant requirement is the host game and any files or version specified on the current Workshop page.

Should I play Spartan Ops before or after Halo 4’s campaign?

After. Xbox Wire describes Spartan Ops as story content that picks up where the main campaign concludes. Treat it as optional only when you are focusing on the central campaign.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Can I skip Halo 3?

You can begin Halo 4 without replaying Halo 3, but Halo 3 is the direct preceding official game and the setting named by the mod’s description. Playing it gives the clearest context for either route.

Can I play Halo 4 on an Xbox 360 today?

The campaign and Spartan Ops remain available on the original release, but Xbox 360 Halo online services were reduced or disabled on January 13, 2022. Local, LAN and other listed features remain distinct from service-dependent functions.

Is MCC affected by the 2022 Xbox 360 shutdown?

No. Halo Support’s notice concerns the original 360 service environment and backward-compatible play of that original release. MCC uses modernized services, although its current store and subscription terms should still be checked.

What if the Workshop mod does not appear?

Recheck the current project page for the supported build, required host game, enabled content and installation location. Do not replace files using an old guide until you have compared it with the creator’s current instructions.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Do multiplayer or Forge matter for the story order?

No. They are optional activities. For the Halo 4 narrative, finish the campaign and then choose whether to play Spartan Ops.

Bottom line on the correct order

For Halo 4 itself, the order is campaign first, Spartan Ops second. For New Covenant, Halo 4 is optional: the project is described as a Halo 3: ODST campaign mod set after Halo 3, not as an official Halo 4 sequel. Choose MCC if you want the modern collection’s service environment, or use the original 360 release with the limitations documented by Halo Support. Before installing the mod, follow the current Workshop page rather than assuming that an older guide or Halo 4 completion is required.

Frequently Asked Questions

Do I need to play Halo 4 before Halo: New Covenant?

No. The Workshop listing describes New Covenant as a Halo 3: ODST campaign mod set after Halo 3. Halo 4 is optional background, not a stated prerequisite.

What order should I play Halo 4 and Spartan Ops?

Play the Halo 4 main campaign first, then Spartan Ops. Xbox Wire describes Spartan Ops as an episodic continuation that starts where the campaign ends.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Is Halo: New Covenant the official sequel to Halo 4?

No. It is a community project hosted on Steam Workshop. Keep it separate from official numbered games and from Halo: Campaign Evolved.

Which version of Halo 4 should I buy?

MCC is the modern route on PC and newer Xbox hardware, but check current store pricing and subscription terms. A used Xbox 360 copy is another campaign route with legacy service limitations.

Can I play the original Xbox 360 campaign offline?

Halo Support says the campaign and Spartan Ops remain available after the January 13, 2022 service reduction. Online-dependent features may not work like they do in MCC.

What do I need to install New Covenant?

Follow the current Steam Workshop page for the required Halo 3: ODST host game, supported build, files and installation method. Exact compatibility instructions can change.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The Bottom Line

Play Halo 4’s campaign, then Spartan Ops if you want its full story. Halo: New Covenant does not require either one: it is a Halo 3: ODST community mod set after Halo 3. Use MCC for modern access, or an original 360 copy with the documented service caveats, and always follow the mod’s current Workshop instructions.
