Mod of the Week: DOOM II

The final title in the catalogue of GZ3Doom compatible videogames should come as little surprise. A mod developed to allow videogames based on the DOOM Engine to be played as virtual reality (VR) experiences on the Oculus Rift, DOOM II is an obvious addition with which to conclude VRFocus‘ series of features on the mod.

DOOM II surely needs no introduction. Launched in 1994, DOOM II came only a year after the original DOOM. The two titles have often been packaged together since and, indeed, alongside DOOM 3 as part of the DOOM 3: BFG Edition package on Xbox 360 and PlayStation 3. A version of DOOM II compatible with GZ3Doom can be found on Steam.

Set-Up

To play DOOM II in VR you must use GZ3Doom in Oculus Rift mode. The first step is to download the GZ3Doom package from Rotating Penguin’s website:

Windows: GZ3Doom 1.8.6_h Installer for Windows (latest version).

Mac OSX: GZ3Doom 1.8.6_h Installer for Max OSX (latest version).

Once installed, find the directory in which the program is held and also the location of DOOM II and drag the ‘DOOM2.WAD’ file on top of the ‘gz3doom.exe’ file, ensuring that neither file changes directory. This will launch DOOM II using the GZ3Doom modification hi-jack.

Once loaded, set the in-game resolution to 1280×800. Launch into the videogame and press “+” until no status bar remains. Next, activate the ZDoom console by pressing “`” (UK Keyboard layout) and input “vr_mode 8”. The screen will automatically adjust to the stereoscopic display associated with the Oculus Rift and be ready to play on the head-mounted display (HMD).

 

Notes:

You can turn off mouse menu selection for Oculus Rift mode: Options->Mouse Options->Enable Mouse in Menus->NO

You can also turn off mouse look for Oculus Rift mode, making the headtracking slightly smoother: Options->Mouse Options->Always Mouselook->OFF

If you dislike the high speed your character moves at, type “TURBO 65” in the console.

You can turn off the head bobbing with the command “MOVEBOB 0” when typed into the console.
