The Lambda1VR application itself won’t work without a copy of the Half-Life game files, which you’ll need to copy over from a computer that has the game installed.īefore proceeding, just make sure you have a copy of the original Half-Life game (not Half-Life 2 or Half-Life: Source) downloaded from Steam, on the same computer that you use SideQuest on. If you’ve followed everything up until that point, you can move on with the guide below. For the purposes of installing Half-Life, you’ll want to follow the sideloading guide right up until the “Sideloading content from the SideQuest store page” section. If you haven’t sideloaded anything before, or don’t even know what that means, check out our guide on how to sideload content on the Oculus Quest.

If you’ve sideloaded content via SideQuest before, then you can move onto the next section.

In order to install Lambda1VR and Half-Life on your Quest, you will need to be familiar with sideloading content on your Quest and make sure your Quest is also in developer mode.
