CHWÆST — Feed the Biomass Core to progress
A late-90s inspired retro 3D horror where progress is biological.
You don’t unlock doors. No keys — you feed the Biomass Core.
CHWÆST takes place inside a living organism. Passages overgrow, corridors tighten, and the environment reacts to your presence.
At the center lies the Biomass Core (the Core) — the only way forward.
Your goal: complete simple objectives, bring offerings back to the Core, and push deeper until you find a way out.
How progression works
The entire environment is a single organism that depends on the Biomass Core being fed.
When the Biomass Core is hungry — passages are blocked
When you feed it — the organism retracts and reveals new paths
Doors are replaced by tendrils. Keys are replaced by food for the Biomass Core.
The core gameplay loop
find → grab → return → feed the Core
objects hidden in darkness that must be carefully spotted
small creatures crawling along the floor
organisms that hide or escape when approached
In the game, you are given clear objectives such as:
Active outgrowth: Mushrooms → Feed the Core (Mushrooms 0/6)
FEED THE BIOMASS CORE — RETRACT OUTGROWTHS (0/5)
Every trip deeper into the tunnels becomes a decision: how far can you go before you must return to the Biomass Core?
One location. Constantly changing paths.
item placement changes each playthrough
you never fully know what you will encounter when you return to the Core
Visual style: how you remember it, not how it looked
low internal resolution scaled sharply
limited color depth and dithering
classic 50/50 transparency effects
subtle geometry artifacts that make the world feel unstable
This is not meant to be pretty. It is meant to feel unsettling and unsafe.
What to expect
a short, intense horror experience (30–60 minutes)
a unique mechanic centered around feeding the Biomass Core
exploration of dark, organic tunnels
minimalist rules and clear in-game objectives
If you enjoy horror that is mechanical, raw, and unpredictable — CHWÆST is exactly that.
