Can this be played using final DOOM wad, or do I have to use DOOM 2 wad?
Viewing post in Doom: The Golden Souls comments
Both Final Doom and Doom 2 are separate games with their own unique content. To run a specific mod or map, you usually need the corresponding base game wad file. So, if you're interested in playing mods designed for Final Doom, you'll usually need the Final Doom mod. Likewise, if the mod is designed for DOOM 2, you'll need a DOOM 2 wad.
The mod must be matched to the correct base gamepad to ensure compatibility and the desired gameplay experience.
