Matrix Runner is a cancelled action adventure game that was in development in 1992 / 1993 by ZCT Systems Group for the Sega VR add-on based on the Mega Drive / Genesis. Players had to explore the cyberspace and to resolve various puzzles to try to capture a murderer. The concept (and the title) of the game is really similar to Free Runner, a cancelled adventure for the Saturn, but as far as we know, the developers are different. It could be just an huge coincidence, or maybe someone from ZTC Systems went to work to Rebellion and resurrected their old project.
Only a single screenshot of Matrix Runner was found by Rod_Wod and Celine in some old magazines. If you know someone that worked on this game, please let us know!
