Catalog: Half-Life 2 · Install the base conversion from the official Half-Life 2: VR Mod Steam page.
Half-Life 2: VR Mod is one of the easiest high-quality flatscreen-to-VR conversions to install because it is available directly on Steam and is free for owners of Half-Life 2.
Unlike a generic injector, this is a dedicated fan-made VR conversion designed around Half-Life 2 itself. That makes it an excellent first PCVR mod for someone who does not want to manage profiles, DLL chains, or multiple compatibility layers.
What you need
- Half-Life 2 in your Steam library.
- A SteamVR-compatible PCVR headset setup.
- Half-Life 2: VR Mod from Steam.
The mod is a separate Steam app but requires ownership of Half-Life 2.
Step 1: Install Half-Life 2
Make sure the base game is owned and installed or otherwise available to Steam as required by the mod.
Launch Half-Life 2 once if you have never played it on this PC. This helps establish the expected game files and Steam configuration.
Step 2: Install Half-Life 2: VR Mod
Open Steam and search for Half-Life 2: VR Mod. Install it like any other free Steam title.

Step 3: Start SteamVR and launch the mod
Connect your headset, start SteamVR, then launch Half-Life 2: VR Mod from your Steam library.
Because this is packaged as a dedicated Steam application, there is no UEVR injection step.
Configure your height and play space
Before progressing far into the campaign, verify:
- Floor height.
- Standing/seated mode.
- Dominant hand.
- Turning style.
- Weapon angle.
- Physical crouch behavior.
A small floor-height error can make doors, desks, and weapons feel consistently wrong.
Motion controls
Half-Life 2: VR Mod adds full VR interaction to a game designed in 2004. Weapons and world interactions are adapted for tracked controllers, making the campaign feel much closer to a native VR shooter than a simple head-tracked conversion.
Do not expect every object to behave exactly like Half-Life: Alyx; the underlying game was designed for mouse and keyboard. The important part is that aiming, locomotion, and interaction are rebuilt around VR.
Comfort settings
Half-Life 2 contains fast movement, vehicles, scripted camera moments, and physics chaos. New VR players should start conservatively.
Recommended first-session options:
- Snap turning.
- Lower turn angle if 45 degrees feels abrupt.
- Seated play if standing during vehicle sections is uncomfortable.
- Short play sessions.
- Comfort vignette if available and helpful to you.
Vehicles in VR
The airboat and buggy can be intense. Being seated physically helps because your body has a stable reference while the virtual vehicle moves.
If you feel nausea, stop and resume later. Do not try to “train” through strong discomfort in one session.
Performance
Half-Life 2 is much lighter than modern AAA UEVR games, so most contemporary VR gaming PCs should have an easier time running it.
If performance is unexpectedly poor:
- Disable extreme supersampling.
- Check SteamVR per-app resolution.
- Close GPU-heavy background applications.
- Update GPU drivers.
- Confirm the headset is not accidentally running at an unusually high resolution multiplier.
The mod will not launch
Try these steps:
- Launch normal Half-Life 2 once.
- Verify Half-Life 2: VR Mod files in Steam.
- Restart SteamVR.
- Remove unusual launch options.
- Disable conflicting overlays.
- Check the project's current support pages for a recent Steam/OS update issue.
Check the project's current support pages because an old troubleshooting post may no longer match the latest release.
Episodes and additional content
The Half-Life 2 VR project also supports the episodic follow-ups through its related VR releases. After completing the base campaign, look for the current VR Mod versions of Episode One and Episode Two.
Is Half-Life 2 VR better before or after Half-Life: Alyx?
Either order works. If Alyx was your introduction to VR, HL2 VR is fascinating because it lets you revisit Valve's older level design from inside the world. If you have never played Alyx, HL2 VR can also provide useful story context.
Quest 2 / Quest 3 setup
Quest headsets can run Half-Life 2: VR Mod as PCVR headsets through Link, Air Link, Steam Link, or Virtual Desktop.
Because the mod uses SteamVR, make sure your chosen connection exposes the headset correctly to SteamVR before launching.
