VR Doom II - Map10 Refueling Base - QuestZDoom

Refueling Base has a reputation for being tight on ammo, but I find it to be nowhere near as tight as most levels in Sigil.

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 mid-level 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)
