Platform Anomaly (co-op)
A downloadable game for Windows
Platform Anomaly — a co-op horror about spotting anomalies.
Team up and sweep a subway platform for the subtle details that feel “wrong.” Whisper theories, argue over shadows, and sometimes laugh when a teammate marks something completely off.

DEMO CO-OP ONLINE (Steam)
Online co-op via Steam: to use the co-op, you need to download the demo version from the Steam website.
Modes
- Standard: Explore the station, find and mark anomalies. Make mistakes and the station gets angry.
- Hide & Seek: One player hides anomalies and watches the others sweat, argue, and (sometimes) fail.
Why it’s fun
- 8–15 minute rounds — quick, tense, “one more before bed.”
- Randomized anomalies — every run feels different.
- Fear flips into laughter — perfect with friends.
Features
- 1–4 player co-op.
- Dozens of anomaly types: light, shadows, sound, geometry, environmental logic.
- Grounded, realistic horror atmosphere.
- Two distinct modes — unusual for the sub-genre.
How to Play (quick)
- Look around and memorize the “normal” state.
- Hunt for changes: missing objects, extra doors, altered paintings.
- Highlight suspicious objects to mark them. Incorrect marks restart the run.
Controls
- WASD — Move
- T — Flashlight
- Right Mouse Button — Interact
