You can play DOOM on practically all game platforms, as well as on many objects that have never been designed for video games (such as calculators and pianos) and now, to date, the list also includes Oculus Quest.
The Quest version of DOOM is via QuestZDOOM, a side launcher that allows you to access free versions of DOOM and other related content, as well as the original DOOM, DOOM II, Heretic and Hexen if you already own those games. QuestZDOOM also includes a list of mods that you can install to improve audio, change the textures of weapons to 3D models or voxel drawings, and even new map packs.
Installation via SideQuest
Two apps are required to be installed to play QuestZDOOM on Oculus Quest: the launcher and the engine. These are two separate APKs that can be installed through SideQuest.
If you’ve never used SideQuest before and don’t know how to use it, you should follow the setup instructions in our guide here. However, if you’ve used it before and know the basic process, all you have to do is install the launcher and the engine via SideQuest and you’re good to go.
You can follow the links above or locate the QuestZDOOM launcher and engine in the Games and Apps tab of SideQuest or in the search bar.
Once installed, launch the “launcher” application from your list of Unknown sources in the Library tab inside the headset. From there you will select which main game files to launch, such as FreeDoom, followed by any other resources or mods you wish to enable.
It’s all fairly simple with many options. The user interface isn’t great for virtual reality, it’s basically a giant window that looks like an old-school PC game launcher, but it works pretty well.
Installation of original WAD files
Now, if you want to use QuestZDOOM to reproduce the original DOOM, DOOM II, Heretic or Hexen, you can do it too, included with some of the fantastic mods available. To do this you must legally own full games already on PC. If not, there are many very inexpensive ways to grab them:
At least I recommend trying the original DOOM (the Ultimate DOOM version works great) to get an authentic retro atmosphere with a blood soaked nostalgia.
Now, to make one of these original ID software games in VR work on Quest, it is very simple:
- Install the apk files for QuestZDOOM and the launcher on Quest by following the previous steps.
- Start the launcher on your mission at least once.
- Install and run the games you want to copy to the headset at least once.
- Browse to the local game installation files. For example, Ultimate DOOM on Steam installed on steamapps / common / Ultimate Doom and from there opens the “base” folder.
- Find the “DOOM.WAD” file and copy it.
- Now connect Quest to the PC and open SideQuest. Wait for the bubble in the upper left corner to be green and the Quest to be fully connected.
- Click the folder icon to open the Quest file browser.
- Scroll down and open the “QuestZDOOM” folder in the Quest directory.
- Open the “wads” folder in this directory.
- Paste the source WAD file for the original ID game you want to play, such as “DOOM.WAD” or “DOOM2.WAD”.
- Close SideQuest and unlink your search.
The first time you open the launcher, some files will need to be downloaded, which can take a minute or two depending on the speed of your Internet connection. You will be able to view the downloaded files under the QuestZDOOM logo. Wait for it to finish, it works like a patcher you could see for a PC or MMO game.
From there everything is organized in columns: main games, maps / conversions, game mods, weapon packs, plots / sounds and other files.
You may notice that upon launching one of the games the main menu is basically a 2D square in the face, but once you actually start the game everything will fall into place as a fully immersive 6DOF experience. Pixelated images feel oddly at home in VR, especially if you enable a weapon pack like voxel weapons or 3D weapons.
Once you enter the game, I highly recommend that you open the Options immediately and take a look at the changes you can make. In “VR Options” you can adjust things like your character’s height if he is feeling out, change the angle of the snap curves, enable teleportation movement, change your walking speed and even change the angle and size of your weapons.
After adjusting them, you should go to the “Customize Controls” menu and assign the Edit Weapons button to something easily accessible, such as one of the grip buttons, and make sure that everything you shoot, interact and jump is easily accessible.
