Play Half-Life Alyx NoVR from Start to Finish on Your Steam Deck Today!


Our Biggest Update Yet!

This is our biggest update yet and we have no plans on slowing down! With thousands playing Half-Life Alyx NoVR we are happy to announce our largest update yet! As the titles state the entire game can now be played from start to finish, with the Gravity Gloves fully implemented along with combine fabricators providing weapon upgrades. Also since we are now updating the final parts of the game there may be spoilers! We will do our best to not spoil anything while ensuring we communicate these late game areas have been updated along with their gameplay mechanics.



The Half-Life Alyx NoVR mod aims to allow anyone to play this amazing game however they like. This is no substitute for the amazing experience this game provides in VR on a headset like Valve’s Index. However, for those with health concerns, motion sickness and other limitations from experiencing it in VR this is a great alternative! It is also a great way to replay the game anyway you like! With its extremely easy install (no drivers!) it makes Half-Life Alyx more accessible than ever.

ORIGINAL ARTICLE


The Half-Life Alyx NoVR mod aims to allow anyone to play this amazing game however they like. This is no substitute for the amazing experience this game provides in VR on a headset like Valve’s Index. However, for those with health concerns, motion sickness and other limitations from experiencing it in VR this is a great alternative! It is also a great way to replay the game anyway you like! With its extremely easy install (no drivers!) it makes Half-Life Alyx more accessible than ever.


In-Game Screenshots of Half-Life Alyx NoVR Running on Steam Deck


Currently the mod allows you to complete the game up to the first parts of Chapter 7, with 11 chapters total the mod is nearing a playable state from start to finish. Let's go through just how easy and flexible this NoVR mod for Half-Life Alyx is!


Steam Deck Installation and Performance Overview

To showcase how easy to use and flexible this mod is, we thought showcasing the mod running on a Steam Deck would really drive that home!


Video guide:


Now first off you will need a copy of the game purchased through Steam. Then download the mod here:



Simply copy the “game” folder from the mod to the folder you have Half-Life Alyx installed through Steam. Then simply add these launch options under properties to the game before launching it with the mod:

-novr -vsync

Then start the game!


Extremely easy and simple. If you want to add access to the console and setup the game to the native resolution of the Steam Deck add these launch options as well:


-console -vconsole -w 1280 -h 800


With this, the game is now ready to be launched! But…we have also created a custom controller layout for Half-Life Alyx NoVR for the Steam Deck! So go to controller options for the game and you should find it in the Community Layouts. Here are all the details to find it along with the link to the controller layout.



Steam Deck Controller Layout for Half-Life Alyx NoVR


This layout can be customized however you like and is a great template to start the game with and work from there. As for performance with the Steam Deck, the game is running at 800p60fps at Ultra Fidelity (all in game graphics settings maxed), with roughly 2.5-3ish hours of battery life when playing Half-Life Alyx NoVR. Source 2 is running very well on Steam Deck and bodes well for Counter-Strike 2! You can play it in handheld mode or connected to your 4K TV or a monitor and playable with a keyboard and mouse. Of course a high end gaming PC will run it easily, just check the minimum and recommended specs for the game on Steam! Those specs are a bit higher than what you will actually need since the game is not running in stereoscopic 3D, and therefore much less demanding.



Current Progress and Future Updates

Currently the game can be completed to the start of Chapter 7 without having to use noclip. If you choose to continue there is quick access to noclip with one button to continue on. With 11 total chapters the game is currently 60% playable with NoVR with future chapters being completed week to week. The goal is to ensure you can finish the game and get to the ending first. Then fine tuning the gameplay entirely. So far many adjustments have been made to make all features playable.


Currently, these mechanics are unavailable and will be added in the future:

  • Combine Fabricators (for weapon upgrades)

  • Secondary weapon fire

  • Gravity Gloves - Experimental Git Branch Only

  • HLA HUD (currently uses the HL2 HUD)

  • Some achievements won’t activate that require the Gravity Gloves and achievements in and past Chapter 7 haven’t been tested yet


Known Issues

The mod is currently in Early Access with not all chapters fully complete at this time. Here are a few issues that are known and the development team is working on:

  • Alyx can sometimes get stuck on the environment, jump and crouch jump to try and get unstuck and use the noclip button if that doesn't work. This can sometimes happen with doors as well.

  • The mod can be used to play Half-Life Alyx mods however your ability to play them may be limited due to not being able to interact with certain items in these maps. Many of the wave-based and arena based

  • There is no way to use the in game menu to adjust settings while playing, you will have to use M on the virtual keyboard to bring you back to the Main Menu to adjust settings before going back into the game.

  • There can be crashes upon level load and loading after death, please restart the game and reload your save.

  • The Gravity Gloves in the separate branch on Git works only for prop objects at this time, not for usable items (resin, health syringes etc). Currently in this form they are great for grabbing items easily to distract barnacles and headcrabs. Along with grabbing explosive canisters easily to throw them for a group kill.

  • Covering your mouth in Chapter 7 "Jeff" works fine when holding "H" however when using this on some other maps it will work but three hands will cover her mouth instead, this is a visual bug only as the mechanic still works even when displaying this way.


Incoming Updates!

We have some major updates already coming in that will be available on the Git in the next few days:

  • Gravity Gloves - The Git branch named "Gravity Gloves" has this gameplay mechanic available and currently works with prop objects only.

  • Covering Your Mouth - Hold "H" to cover your breath to not make sound in Chapter 7 "Jeff"

  • Chapter 7 Update - This chapter will soon be completable from beginning to end

  • Chapter 8 Update - This chapter will soon be completable from beginning to end

  • Chapter 9 Update - This chapter will soon be completable from beginning to end

Please check the Git page regularly as that is where daily work is posted for anyone to check out! ModDB file updates will happen in larger updates like this one.
