A downloadable game for Windows

Platform Anomaly — gameplay

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.

Searching for anomalies

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.

Marking an anomaly

How to Play (quick)

  1. Look around and memorize the “normal” state.
  2. Hunt for changes: missing objects, extra doors, altered paintings.
  3. Highlight suspicious objects to mark them. Incorrect marks restart the run.
