About WARD 13 — Anomaly Protocol
WARD 13 — ANOMALY PROTOCOL
You have been admitted to Ward 13.
Walk through 25 L-shaped hospital corridors. At the end of each ward,
decide: did you spot an anomaly — something wrong, missing, moved, or
out of place — or was everything normal?
25 correct assessments to be discharged. One mistake ends the run.
── FEATURES ──────────────────────────────────────────────────────────
🏥 ATMOSPHERIC 3D ENVIRONMENT
An L-shaped hospital corridor rendered in real-time 3D. Yellowed tile
walls, stained linoleum floors, drop ceilings with flickering fluorescent
lights. Everything procedurally generated — no external assets needed.
🔬 20+ UNIQUE ANOMALY TYPES
Each ward may contain one of over 20 different anomalies:
• Blood puddles on the floor
• Bloody handprints on the walls
• A light that has turned red
• A flickering or extinguished light
• A missing gurney or wheelchair
• A gurney that has tipped over
• The clock hands pointing the wrong way
• The EXIT sign arrow flipped backwards
• A patient monitor that has switched on
• A "HELP ME" warning sign
• A shadow figure on the wall
• A ceiling stain that wasn't there before
• A door left open (revealing darkness)
• Extra equipment that shouldn't be there
• And more...
🎮 SIMPLE, TENSE GAMEPLAY
Move with WASD. Look with the mouse. Walk to the EXIT at the end of
each corridor. You have 15 seconds to make your call:
Z = Anomaly detected
X = All clear
⏱ PROGRESSIVE DIFFICULTY
Level 1 is always normal — a tutorial to study the layout. From Level 2
onward, roughly 60% of wards contain an anomaly. The anomaly types
rotate, so you always face something different.
🔊 ATMOSPHERIC AUDIO
Procedural footstep sounds, ambient drips, feedback tones. All generated
with the Web Audio API — no audio files to download.
