Cyber Tech Games III: Capture the Ghost

October 29, 2025

A while ago, while diving into our archives, we stumbled upon some unreleased material that hadn't seen the light of day in decades. We asked our colleagues to analyze it digitally to recover its content… but instead, they turned it into the new challenge of Cyber Tech Games.

It's a video recording made on a Halloween night, somewhere in an unknown city, sometime between the 1980s and 1990s. The author: a paranormal enthusiast who claimed to have captured something supernatural.

And alongside that video, we found an EVP recording captured that same night, in the stillness of the early hours.

We’re sharing both files so you can carry out your own investigation into the secrets they might be hiding. You can download them below and analyze them your way.

Can you uncover the hidden message* that has waited nearly three decades to be revealed?

(*) The hidden message could be in any language.
