VR Doom II - Map24 Chasm - QuestZDoom

The Chasm is the Nickelback of Doom II maps; everyone loves to hate it, but it's nowhere near the worst.

VR tip: The ledges cannot be safely traversed with the thumbstick, since there will always be unintended left-right movement. Instead, map one of the buttons to move Doomguy forward in a perfectly straight line, similar to the W key on a keyboard. My 'forward button' is the left trigger. Use your body to turn, as normal.

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).

Duplicate music tracks were replaced with the ones from the community-made "MID the way Id did" pack. https://tinyurl.com/4jhth4m9
