VR Doom II - Map02 Underhalls - QuestZDoom

I'm attempting to beat Doom II on the Meta Quest 2 (virtual reality headset), played through QuestZDoom on the Ultra Violence difficulty.

Again, I'm going for 100% kills and 100% secrets; all maps from a pistol start; no jumping, crouching, or saves.

Mods: Alternative Vanilla 3D Weapons (except chainsaw & SSG from HDVRweapons_Quest_Plus_v1.0; and rocket launcher & plasma rifle from alek_DoomGuns_v1.1a); Customized MIDI soundfont (using Merlin, Chorium, Roland, and self-made samples); Voxel mod (by Cheello) is enabled on some smaller maps.
