Why it is worth attention

It brings two classic Halo games into VR with full 6DOF head tracking and motion controller integration, developed by a single human modder using AI-assisted coding, and is one of the few VR mods for the MCC that supports native cutscenes and game mechanics.

Who it is for

Halo fans wanting to play MCC in VR
VR gamers looking for first-person shooter experiences
Modders interested in OpenXR mods for legacy games
Players who enjoy experimental alpha software

Use cases

Playing Halo 3 campaign missions in immersive VR
Experiencing Halo 3: ODST with motion-controlled weapons and hands
Testing a community-developed VR mod with configurable comfort options
Learning about reverse-engineering and OpenXR modding through the documented evidence

Strengths

Supports per-eye stereo rendering and 6DOF head tracking
Motion controller input with weapon aim, arm IK, grenades, and melee
Native HUD and floating weapon crosshair with scopes
Works with Halo 3 cutscenes, death/respawn, and mission transitions

Considerations

Alpha quality with known issues (e.g., ODST opening cutscene may be black, brightness locked at default)
Requires specific MCC settings and SteamVR as default OpenXR runtime; no installer
May be flagged by antivirus as unsigned injection mod
Author may abandon the project at any time and code was not fully human-reviewed

README quick start

REACH/3/ODST Now Playable in VR

Work on HALO 4 will begin SOON after these hotfixes release. Yes Halo 1/2 will be in the collection eventually!

GAMEPASS IS NOT SUPPORTED ATM, A HOTFIX IS OTW FOR THAT!

ALVR Support and default Steam VR branch is being looked into

🚧 What I'm working on RN

Feature	Status
ALVR Support (double vision fix)	🟡 In Progress
Halo: Reach Visual/UI Fixes	🟡 In Progress
Space-Sky Bloom Bug Fix (Halo Reach)	🟡 In Progress
Xbox App / Game Pass Support	🟡 In Progress
SMAA T2X Support	🟡 In Progress
Optional 2D Theater Mode for Cutscenes	🟡 In Progress
Gamepad support/Head-Aiming Mode	🟡 In Progress
Scopes and weapon zoom fixes	🟡 In Progress
Complete F1 Menu UI Restructure and Reorganization	🟡 In Progress

Note: The optional 2D theater mode will be enabled by default for cutscenes, but players will be able to disable it.

DO NOT ACCEPT FIXES FOR THIS MOD FROM OUTSIDE SOURCES. WE DON'T KNOW WHAT'S IN THEM.

Two things are required:

The SteamVR Beta. A user reported that it fixes the double vision.

SteamVR set as your default OpenXR runtime.

Compatibility across headsets may vary. If it doesn't work, try a different way to connect if you can — but follow the two requirements above and you should be good.

Let me know in the issues if your headset is not working and someone or I can help you.

For a GPU performance boost, try Quad-Views-Foveated.

Please list your specs if you're having issues. It's a guessing game over here.

Halo MCC VR

Hi, I'm pancreations — a 3D animator. I really don't like AI art, but I also really want to play MCC in VR, so I'm taking one for the team. Follow me on Instagram if you like silly animations made by humans in Blender. ([Expect me to quit at any moment.](https://www.youtube.com/watch?v=
