Halo 5 Campaign on PC

A small hobby project to get the Halo 5: Guardians campaign running on PC through the existing Halo 5: Forge PC build.

All 15 missions are now fully playable. A few kinks to iron out, but it's getting there.

I'm mainly making this because I want to speedrun Halo 5 on PC. That's pretty much the goal. No plans for multiplayer, matchmaking or the rest of the Xbox services.

The Discord is for help and support with the tool. No sharing game files, prepared caches or links to download them. Please don't ask for them either.

Sponsoring supports me personally as a developer. It doesn't get you game files, private builds, priority support or any other special treatment.

Outstanding bugs

• Lots! Still a work in progress
• Checkpoint reverts not working.
• Launcher doesn't recognize the game if it is on a different drive
• Lots of crashes!

Find a bug? Please report it on the GitHub issues page.

What you need

• A Windows x64 PC and a local NTFS drive for the cache.
• Halo 5: Forge Bundle from the Microsoft Store, including the Halo companion app. Tested with Forge 1.194.6192.2.
• Your own extracted Halo 5: Guardians game files, tested with 1.1.31695.21, or a complete compatible launcher cache.

Game files are not provided. English (US) is currently supported.

Getting started

1. Download the launcher from Releases and extract the ZIP.
2. Open h5sololauncher.exe, select your extracted game files and a cache destination, then click Prepare & play.
3. In Solo, choose a mission and play.

Already have a complete cache? Select it and click Play. You don't need the original game dump to play from a complete cache.

Missing missions in an older cache? Select your extracted game files and use Options and diagnostics > Prepare cache only. Updating the launcher alone won't add the missing mission files.

Fair warning

A lot of this is vibe coded. I'm not going to pretend I understand all of it, and things will probably break.

It works on my PC, though!

This isn't Halo 5: Reforged

This is a separate hobby project, not Halo 5: Reforged. I'm just focused on getting the original campaign working as well as I can.

Game files

Halo 5 game files are not included in this repository and will not be distributed by this project.

You'll need to provide your own copy of the required campaign data. Please don't open issues asking me to upload or provide it.

Support me

Sponsorship is completely optional and supports me personally as a developer. It isn't payment for Halo 5 or access to any game files.

There are no sponsor-only builds, early access, priority support or fixes, or any other special treatment. Everyone gets the same public releases, and sponsors still need to provide their own game files.

Bugs and contributing

If something breaks, open an issue with what you were doing and the output from Copy details in the launcher.

If you know your way around Halo 5, Forge or its file formats, help is always welcome.

Halo Studios

If you're reading this, I'd happily work on an official Halo 5 PC port for free. Give me a shout. Would save me doing it the awkward way.
