S1LSD — a fictional LSD substance for Schedule I

Version 0. 11. 0 · Schedule I 0. 4. 6 (IL2CPP) · MelonLoader 0. 7.x · S1API 3. 2.x

Photosensitivity warning. This mod distorts the picture (warping, texture crawl, colour and light changes, geometric patterns with closed eyes) and changes the sound. Brightness and colour changes are smoothed in software so they never pulse faster than 3 times per second, but this is not a medical guarantee. If you are sensitive to flashing or moving images or prone to motion sickness, turn on Gentle Mode (lsdgentle on) or do not use this mod. Stop any time with F7 → STOP TRIP or lsdstop.

Fiction. A video-game item only. No real-world dosing, acquisition or chemistry information; production uses abstract in-game ingredients.

AI-generated content. Most of the code was written by AI agents under human direction and testing.

What's new in 0. 11. 0

  • []Own perception shader: surfaces breathe and crawl where they have texture (outlines stay put), real trails behind moving and bright things while the still world stays sharp when you turn, geometric forms surfacing in the dark and at the edge of vision from 140 µg, deeper colour on weak tones, a thin colour fringe on edges.[/]

    []Bad trips develop from anxiety instead of switching on: police, injuries, crowds and driving raise it; home, music and stillness lower it. Hold V and breathe to stop a wave or shorten a bad trip; relief follows.[/]

    []Anxiety and calm colour the whole trip; your heartbeat speeds up with anxiety and you hear and see it.[/]

    []Taking more during a trip makes it stronger and longer instead of restarting it; every trip is a little different.[/]

    []New item look: a blotter sheet (1 / 2 / 2×2 / 3×3 tabs by dose) in the hand and on shelves; packaged LSD shows its tabs inside the game's own baggie or jar, also in the inventory icons and at the Packaging Station. Taken under the tongue — no more snorting, no mushroom in third person.[/]

    []Fixes: every game patch was applied twice; packaged LSD looked empty; a second dose restarted the trip.[/]

    What it adds

    Four doses — 70, 140, 280 and 360 µg (game values). Each follows onset → come-up → peak → plateau → comedown → afterglow over 3. 5 to 11 real minutes, with slow, irregular waves of intensity.

    Visuals — two styles:

    • []Classic (default): strong. Surfaces crawl and breathe, space slowly swells and settles, colours deepen, lights get halos. At 280–360 µg straight lines visibly bend, but you always know where you are.[/]

      []Subtle: lines stay straight; the movement stays inside surfaces.[/]

      Colours deepen the scene's own palette instead of laying a rainbow over it. S1LSD's own shader makes surfaces breathe and crawl where they have texture, leaves trails behind moving and bright things while the still world stays sharp, and lets geometric forms surface in the dark and at the edge of vision on strong doses. Hold B to close your eyes during a trip: a dark field, then geometry slowly fading in.

      Sound — a room that grows (reverb), a short echo, a light chorus, soft muffling that follows the breathing, and quiet ambience generated in code (a low drone and faint overtones). Music and loud sounds gently drive light and colour.

      Set and setting — police nearby, injuries, crowds or driving make a trip tense; home, music and stillness calm it. A small share of doses (2 / 4 / 7 / 12 %) brings a wave of anxiety, and where you are decides whether it turns into a bad trip: cold colour, a tunnel that tightens with your heartbeat, shadows at the edge of vision, heavier sound. Hold V to breathe it down; sleeping ends it; relief follows. Taking more during a trip makes it stronger and longer instead of starting over.

      The item — a sheet of blotter tabs (1, 2, 2×2 or 3×3 by dose) that you place under your tongue. Pack it at the Packaging Station into the game's own baggies or jars: the tabs stay visible inside, in the world and in the icons, and you can take a tab straight from a baggie.

      Tolerance — each dose builds it, it halves every two game days, and it weakens and shortens the effect. Saved per player.

      Economy — Chemistry Station recipe (Megabean + Acid → 4× 70 µg), discovery in the Product Manager after the first batch, NPC samples and deals, optional supplier shops.
