The doors to Zomb Zerro 999 have opened.

You weren’t supposed to be here yet. But now that you are…

This demo gives you a glimpse into the systems beneath the surface - a 30–45 minute descent into fractured logic, tension, and wrongness. It’s not the full horror. Just enough to know it’s real.

What’s inside:

Core gameplay mechanics

Subtle psychological dread

Glimpses of… something you’ll wish you hadn’t seen

Play the demo now on Steam

If you find a way out, let us know. Otherwise, we’ll assume you’ve joined the others.
