The popularity of GZ3Doom as a modification tool continues here at VRFocus, and as such it was deemed necessary to introduce a new title into the fold. With Hexen proving to be a welcome addition to the modified virtual reality (VR) field a step back even further is obviously required: Heretic: Shadow of the Serpent Riders features in this week’s column.
Heretic: Shadow of the Serpent Riders was built upon the DOOM Engine and released in 1996 as a revised version of the original Heretic made available via retail stores for the first time. The sister release, Hexen, proved that gamers were hungry for more fantasy-based first-person shooter (FPS) action and Heretic: Shadow of the Serpent Riders was the answer before a full sequel was to be launched in 1998. Below is the information required to get this classic title running with the aid of the popular GZ3Doom mod package.
In order to play Heretic: Shadow of the Serpent Riders in VR you must first install the GZ3Doom. To do this, 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 Heretic: Shadow of the Serpent Riders and drag the ‘HERETIC.WAD’ file on top of the ‘gz3doom.exe’ file, ensuring that neither file changes directory. This will launch Heretic: Shadow of the Serpent Riders using the GZ3Doom source code.
Once launched, 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 “~” 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).
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.
